Summary

Some non-wall parametric panels still use generic meter-based numeric controls while the viewer is in imperial mode.

PR #321 fixes the selected wall metadata panel and centralizes shared linear measurement formatting. This follow-up tracks the broader audit/migration so #321 can stay scoped.

Candidate areas to audit

• Door/window panels
• Roof panels
• Column panel
• Slab panel
• Fence inspector editors
• Any other SliderControl usage that represents linear scene values stored in meters

Expected behavior

When the viewer unit is imperial, editable linear controls should display/edit in feet while continuing to persist scene values internally in meters.

Notes

Use the shared measurement helpers from @pascal-app/editor where appropriate, or introduce a shared imperial-aware control if that keeps repeated panel code smaller.
