Encode the Login Error Page URL and Cover More Windows Path Forms

The login dialog's error page was still loaded from a raw resources path; it now uses file_url_from_path like the other local pages. The Windows file URL tests now also cover a resources path joined with a forward-slash relative path, as the callers build them, and a UNC path.
Percent-Encode Local File URLs for Embedded Web Pages

-# Printer agents
-
-Printer agents isolate printer-specific communication from the rest of OrcaSlicer. The GUI and
-`DeviceManager` operate on a shared set of printer operations and device state; a selected printer
-agent implements those operations for a particular printer ecosystem. The agent boundary allows
-Bambu, Moonraker-based printers, built-in integrations, and Python-provided integrations to use the
-same application workflow without making the GUI understand every printer protocol.
-
-The current boundary is an adapter boundary around the existing application contract. In particular,
-some request fields and message payloads still use the Bambu-shaped representation that existing
-`MachineObject` and `DeviceManager` code consumes. The printer agent is responsible for translating
-that representation into the protocol spoken by its printer. This is an intentional compatibility
-constraint of the current design; the interface is not yet a neutral printer protocol.
-
-The v1 dialect migration path is deliberately narrow. `DeviceManager` currently speaks the Bambu JSON
-dialect because that is the payload shape already used throughout the command and state workflow. The
-v1 `OrcaPrinterAgent` also accepts that Bambu dialect. Its transport path places the small translation
-needed for the target printer at `deliver_to_sink`, keeping the compatibility code at the edge rather
-than spreading it through `DeviceManager` or the agent interface.
-
-The eventual direction is for `DeviceManager` to produce an Orca JSON dialect. The Bambu agent will then
-own the translation from Orca JSON to Bambu's protocol, while `OrcaPrinterAgent` can forward the Orca
-payload directly to its sink. The v1 translation at `deliver_to_sink` can then be removed without
-changing `DeviceManager`, the command callers, or the rest of the agent workflow.
-
-## Components
-
-The system has four relevant layers:
-
-```text
-GUI / DeviceManager / MachineObject
-              |
-        NetworkAgent
-          /       \
- IPrinterAgent   ICloudServiceAgent
-      |                 |
- printer protocol   authentication and cloud services
-```
-
-### `DeviceManager` and `MachineObject`
-
-`DeviceManager` owns the application-facing printer workflow. It maintains `MachineObject` instances,
-updates their state, filters devices for the active printer agent, and initiates operations such as
-homing, temperature changes, printing, subscriptions, and camera playback.
-
-`MachineObject` remains the shared state model used by the GUI. It does not contain the implementation
-of a printer protocol. When a device is discovered or returned by a cloud query, the device is tagged
-with the active `printer_agent_id`. Device lists and selected-machine operations use that tag to avoid
-sending an operation through an agent that does not own the device.
-
-### `NetworkAgent`
-
-`NetworkAgent` is the façade used by the GUI and `DeviceManager`. It owns:
-
- the currently selected `IPrinterAgent`;
- the registered cloud-service instances, indexed by provider;
- callbacks shared by the active printer agent and the application;
- the forwarding methods for printer commands and cloud operations.
-
-There is one active printer agent for the currently selected printer preset. Switching the preset
-increments the machine-list generation, disconnects the old printer agent, removes its callbacks, and
-installs the newly selected agent. The façade then forwards printer operations to that agent.
-
-Cloud operations are selected separately using a provider key. `NetworkAgent` forwards a cloud request
-to the matching `ICloudServiceAgent`, and forwards cloud camera operations with a device ID. The
-printer agent receives a cloud-agent pointer through `set_cloud_agent()` when it is created, allowing
-printer communication to obtain cloud tokens without depending on a concrete cloud implementation.
-
-### `IPrinterAgent`
-
-`IPrinterAgent` is the printer-facing contract. It covers:
-
- cloud-relay and direct-LAN message delivery;
- LAN connection, discovery, binding, and certificates;
- printer subscriptions and callbacks;
- print operations;
- filament synchronization;
- camera capability and local camera URL reporting;
- printer command methods.
-
-Concrete built-in implementations include the Bambu wrapper, the native Orca/Moonraker path, and
-other printer-agent implementations registered by the application. A printer agent may use either
-the cloud agent, a direct LAN connection, or both.
-
-### `ICloudServiceAgent`
-
-`ICloudServiceAgent` owns authentication and services provided by a cloud backend. It covers login
-state, tokens, user and printer lists, settings synchronization, model services, cloud messages, and
-cloud camera operations.
-
-Cloud camera operations are device-scoped:
-
- `get_camera_url(dev_id, callback)` obtains a stream URL for one device;
- `create_camera_signaling_channel(dev_id)` creates signaling for one device where the provider
-  supports it.
-
-This is separate from the local camera URL exposed by `IPrinterAgent`, which is currently scoped to
-the active printer agent because a normal LAN agent represents one physical printer connection.
-
-## Agent registration and selection
-
-`NetworkAgentFactory` maintains the printer-agent registry. Each registry entry contains an agent ID,
-a display name, and a factory function. Built-in agents register during application initialization.
-Python printer-agent capabilities register dynamically and contribute an agent ID and factory entry.
-
-The selected printer preset contains the printer-agent choice. If no explicit choice is stored, the
-application preserves the existing default behavior: Bambu presets select the Bambu agent and other
-presets select the native Orca agent. When a preset is changed, `GUI_App` resolves the effective agent
-ID, obtains the corresponding cloud agent, creates the printer agent through the registry, and installs
-it in `NetworkAgent`.
-
-The registry rejects conflicting agent IDs. This matters for Python plugins because an agent ID is the
-stable identity used by presets and device ownership; two enabled plugin capabilities must not claim
-the same ID.
-
-## Message and command flow
-
-There are two low-level message paths:
-
- `send_message()` publishes a command through the printer's cloud relay;
- `send_message_to_printer()` sends a command directly to the printer over the LAN path.
-
-Both paths accept a JSON string, quality-of-service and flag values, and return the existing network
-status code domain. The agent owns the conversion from that JSON contract to its native transport.
-
-The typed `command_*` methods are the application-facing convenience layer. The five generic defaults
-currently implemented by `IPrinterAgent` construct the existing JSON dialect and route through the
-same message path:
-
-| Method | Default operation |
-| --- | --- |
-| `command_xyz_abs()` | Send `G90` for absolute positioning |
-| `command_auto_leveling()` | Send `G29` for bed leveling |
-| `command_go_home()` | Use the supported homing operation or send `G28` |
-| `command_set_bed()` | Use the supported bed control or send `M140` |
-| `command_set_nozzle()` | Send `M104` for nozzle temperature |
-
-These are compatibility defaults for common printer workflows, not a guarantee that every firmware
-implements every command identically. An agent can override a method when its protocol needs another
-operation. For example, a Klipper configuration may use `BED_MESH_CALIBRATE` instead of `G29`.
-
-The remaining common command methods default to `ORCA_NETWORK_ERR_CMD_NOT_SUPPORTED` because their
-existing behavior is vendor-specific or has no portable implementation:
-
- AMS RFID refresh;
- AMS calibration;
- AMS tray selection;
- camera start;
- axis control.
-
-The methods remain on the common interface so an agent that supports them can override them explicitly.
-`sequence_id` remains part of the command contract because `DeviceManager` creates and tracks it as
-the command ID.
-
-## Device ownership and stale responses
-
-Printer-agent ownership is represented by `printer_agent_id` on device records and `MachineObject`
-instances. The active agent ID is attached when a device is discovered, returned by a cloud list, or
-reused after a preset switch. Local-machine configuration also persists the agent ID so a saved LAN
-device is not silently reused by an unrelated agent.
-
-Cloud printer-list responses carry three pieces of request context added by `NetworkAgent`:
-
-```text
-provider   cloud provider used for the request
-agent_id   active printer agent when the request was made
-generation machine-list generation when the request was made
-```
-
-`DeviceManager` accepts the response only when those values still match the current provider, active
-agent, and generation. This prevents a slow response from the previous preset or provider from
-repopulating the current device list.
-
-The provider mapping is currently selected by `GUI_App`: the Bambu agent maps to the Bambu cloud
-provider and other agents map to the Orca cloud provider. The generation check protects that existing
-selection from races; it does not make cloud-provider ownership intrinsic to an agent. Cloud-printer
-ownership and the broader Orca cloud services are therefore still separate architectural concerns.
-
-## Python printer agents
-
-`PrinterAgentPluginCapability` implements `IPrinterAgent` directly. The live capability object is
-registered with `NetworkAgentFactory` and handed out as the printer agent when its agent ID is selected.
-The plugin receives the selected `ICloudServiceAgent` through `set_cloud_agent()` just like a built-in
-printer agent.
-
-Python plugins must implement the core communication and lifecycle methods required by the interface,
-including agent metadata, printer connection, discovery callbacks, and the two message-send methods.
-Methods that are meaningful only to a particular printer are optional overrides where the C++ base
-class provides a default.
-
-All ten `command_*` methods are available in the Python binding and in the trampoline. Their override
-status is intentionally optional:
-
- the five generic commands use the C++ default when Python does not override them;
- the five vendor-specific commands return `NOT_SUPPORTED` unless Python supplies an implementation;
- a Python implementation can replace either behavior for its own protocol.
-
-The Python camera binding exposes HTTP, HTTPS, RTSP, and HTTP-snapshot modes. WebRTC remains a
-built-in C++ camera mode, but is not exposed as a Python mode because the current Python capability
-does not provide the corresponding cloud signaling-channel contract.
-
-## Camera playback boundary
-
-The camera stream mode describes how a stream is obtained; it does not by itself define ownership of
-the wxWidgets view that renders it. `MediaPlayCtrl` selects and tears down the active backend, while
-the wx parent owns the child window or renderer. This is important because a web view, native media
-control, and frame-based/WebRTC renderer have different wx window-lifetime requirements.
-
-Cloud URL and signaling requests are routed through `NetworkAgent` to the cloud provider selected for
-the device. Local URL requests are routed to the active printer agent. The distinction keeps cloud
-account services device-scoped while preserving the current one-LAN-agent/one-printer model.
-
-## Compatibility constraints
-
-The printer-agent boundary intentionally preserves several existing application contracts:
-
- Bambu-shaped JSON is still the shared command representation;
- existing network status codes are reused, with Orca-specific unsupported/capability errors added
-  in the Orca-reserved range;
- `MachineObject` remains the shared device-state model;
- preset and local-machine data retain compatibility with the existing agent-selection behavior;
- Python plugins use the existing capability and pybind11 registration system.
-
-The agent abstraction is therefore responsible for containing vendor differences, not for pretending
-that all vendor protocols are identical. The planned Orca JSON dialect is the protocol-neutral command
-model for the `DeviceManager`/agent boundary. Once it is introduced, Bambu-specific translation remains
-inside the Bambu agent and the Orca agent's v1 sink adapter can be removed as a self-contained cleanup.
