feat(navigator): wrap sub-views in WidgetErrorBoundary

Each of the 5 Navigator sub-views (RoomCreator, DoorState, RoomInfo,
RoomLink, RoomSettings) is now wrapped in its own WidgetErrorBoundary so
a crash inside one no longer takes down the others. Matches the pattern
already applied to the 13 room widgets + 20 furniture widgets.

Zero behavioural change in the happy path. yarn typecheck +
yarn test --run + yarn lint:hooks all clean (only the 3 pre-existing
floorplan failures remain, unrelated to Navigator).
