* Fix aligned back seam positioning for mirrored objects
This change makes “Aligned back” seams behave the same on mirrored models as on normal models.
Mirroring flips the model’s surface directions, so the slicer treated the back as the front.
Now it corrects those directions when calculating seam visibility, so seams still line up on the back after mirroring.

Fix layer/time display in Preview legend for pause/custom G-code
The Preview legend showed incorrect layer numbers and elapsed time for pause/custom G-code entries. The issue was caused by:
• get_layer_id_at() performing a strict upper_bound search on float Z values, while custom G-code stores Z positions as doubles. Minor precision differences often pushed the lookup to return layer 0 or the last layer.
• The legend displayed the raw zero-based layer index.
Fixes included:
• Fetch layer Z values as doubles and use an epsilon-based closest-layer search.
• Display layers as 1-based values for user-facing UI.
• Accumulate time up to the beginning of the identified layer.
This aligns the legend with the vertical slider marker and provides consistent pause/custom G-code reporting.
### What was the issue?
The check that validates whether a filament is compatible with the selected build plate type was only executed for Bambu Lab printers.
Other printers skipped this entirely, even though they can also use multiple plate types with different temperature requirements.
This caused cases where:
- incompatible filament/plate combinations went unnoticed,
- users received no warning even when the bed type clearly couldn’t support the selected filament.
### What’s changed?
- The validation block extends beyond BambuLab printers.
- Now all printers get the same compatibility check:
- if a filament requires a bed temperature not supported by the chosen plate,
- Orca shows the same clear error message as it does for BBL printers.
- Show the selected filament preset name (alias if present) in bed/filament mismatch warnings instead of substituting the parent preset.
### Why this helps
- Consistent behavior across all printer brands.
- Prevents invalid filament/plate setups that could cause print failures.
- Makes plate presets more robust and predictable for custom and community printers.
### Notes
- No behavior changes for BBL printers — they keep the existing checks.
- Other printers now benefit from them too.
This PR fixes an issue where certain characters (for example the degree symbol ° used in °C) became corrupted after opening and saving the Custom G-code editor multiple times.
#### What was the problem?
When users added symbols like ° inside Start/End G-code, the editor would show them correctly the first time, but after reopening the dialog a few times the text would slowly change into strange characters.
#### How to reproduce
- Open any Custom G-code field
- Add a line containing °C
- Save the dialog
- Reopen it several times
- The text begins to change into unreadable characters
#### What this PR changes
The Custom G-code editor now properly loads and saves text that contains symbols such as °, so these characters stay exactly as the user typed them. This keeps Custom G-code stable across editing sessions and prevents slow corruption of Unicode characters.
#### Result
- °C and similar symbols remain correct
- No more “weird characters” appearing after multiple reopen/save cycles
- Custom G-code is preserved accurately

Refresh filament setting overrides on preset change
The filament “Setting Overrides” page derives its UI state from multiple configs
(filament, printer, process), but this derived state was not recomputed during
preset reloads.
As a result, override widgets could reflect stale values until the page was
revisited or a user interaction triggered an update.
Recompute the filament setting overrides as part of TabFilament::reload_config(),
keeping the derived UI in sync with the active preset immediately after reload.
Fix object list name refresh after emboss edits
Refresh the object list immediately after embossed text name changes so the displayed name stays in sync.
Fix filament preset undo/dirty tracking to match Bambu behavior
Use deep compare for filament presets so vector options report #idx keys.
Align undo/dirty mapping with indexed fields and Bambu’s filter_diff_option.
Pass explicit indices for filament override fields.
Add missing filament variant keys (retract lift bounds, ironing overrides) to filament_options_with_variant so per‑filament undo works.
Spiral Z-Hop resolution
Use slicing resolution to determine segment count for emulated spiral Z-hop
What’s changed
The number of linear segments used to approximate a spiral Z-hop is now derived from the PrintConfig resolution value.
The segment count is clamped to a safe range (4–24) to avoid excessive G-code generation or MCU queue overflow.
Why
Previously a fixed 24 segments were always used, regardless of model resolution.
For small-radius spiral lifts this was excessive and could overwhelm some printers.
Adapting segment count to resolution ensures smooth motion where needed, but lighter G-code where possible.
Details
m_resolution is now stored via apply_print_config().
_spiral_travel_to_z() uses this value to compute segment count dynamically.
Only the linear-segment fallback path is affected; G2/G3 arc-fitting remains unchanged.
