Merge main into Pallet-placement

Resolved conflicts:
- app/update/mod.rs: keep the dock's dock_open_at_default for the XREF
  manager; take main's stable xref row identity (row_index(&id)).
- app/view/mod.rs: keep the edge layout from app::dock; drop main's copy
  of the old edge-stack code (main only reformatted it there).
- ui/window/layers.rs: keep main's new visible_indices next to the
  branch's view_panel.
Files the branch only reformatted take main's version. Adds the Lao
(lo-LA) translations for the new dock texts.
