feat(layers): implement row context menu and actions

- Add right-click context menu on layer, group, and object rows:
  - Options... / Layer Options... / Options for Selection...
  - Duplicate <name> / Duplicate Selection
  - Delete <name> / Delete Selection
  - Lock Others / Unlock All Layers
  - Hide Others / Show All Layers
  - Locate Object
  - Collect for Export
- Select unselected row on right-click; preserve multiselection if already highlighted
- Dispatch actions via registered engine commands with Undo/Redo tracking
- Add headless egui tests covering selection, dispatch, and state integrity
- Update gaps and ui-parity documentation for G12
