## Summary

Follow-up to the feature/OrcaSonar review. Scopes the new behavior to the
OrcaSonar agent, fixes several AMS-sync and lifecycle bugs, and makes the
MQTT tests run in CI. Non-OrcaSonar agents keep their existing behavior.

## Changes

Discovery
- Gate the background SSDP scan to a configured OrcaSonar machine instead of
  running for every non-BBL profile; drive discovery on demand from the
  machine-select popup and back off idle rounds from 5s to 60s.
- Add NSLocalNetworkUsageDescription and NSBonjourServices to both macOS
  Info.plist templates.

AMS sync
- Resolve id-less printer-set trays by material type in get_ams_cobox_infos
  and the sidebar badge loop, matching sync_ams_list, so combo arrays and
  badges stay aligned.
- Keep a printer-set tray that resolved by type out of the "unknown or
  incompatible filaments" dialog.

AMS device UI
- Gate the "Empty" tray classification, and the editable temperature fields,
  to the OrcaSonar agent; Bambu keeps "?" and read-only presets.
- Validate AMS material temps on confirm: reject out-of-range values and
  min > max before the command is sent.

Storage tab
- Bind the show/hide handler on the panel's ancestors (StoragePanel and
  MonitorPanel) and unbind on destruction, so the Bambu file system stops
  when the tab is left.

Transport
- Load /etc/ssl/cert.pem on macOS in add_platform_root_certificates, after
  set_default_verify_paths.
- Release lifecycle_mutex before start()'s connect wait so stop() can cancel
  the attempt and signal completion instead of stalling the UI thread.

Localization
- Add OrcaFilesPanel.cpp to list.txt and regenerate the catalogs.

## Tests
- Un-hide the loopback MockBroker integration tests (ephemeral port, no
  network) so ctest registers and runs them.
- Mock broker tracks SUBSCRIBE/UNSUBSCRIBE and delivers push_report only to a
  subscribed topic; the reconnect test asserts the re-SUBSCRIBE.
- Add bbl empty-tray cases, an AMS combo-alignment case, and unknowns
  assertions to the AMS sync tests.
