feat(timetable): TanStack queries + mutations with optimistic move + cascade pulse (Session 4 steps 3+4)
useTimetable.ts (read side):
- useStages / usePerformances(?day=) / useWachtrij(?stage_id=null)
- useEngagement (popover deal info + advancing aggregate)
- useTimetable() aggregate with isLoading/isError/refetch
- 30s staleTime + refetchOnWindowFocus for multi-user awareness (RFC D14 — Echo deferred to ART-15)
useTimetableMutations.ts (write side):
- move (RFC D18) — optimistic patch on mutate, applies cascaded[] on success,
snapshot rollback on 409 (VersionMismatch surfaced to caller for toast)
- park / unpark via the move endpoint with optimistic stage_id flip
- create / updateNotes / remove + stage CRUD + reorderStages (optimistic) + replaceStageDays
- Idempotency-Key generated per logical action (re-drag = new key)
Skipped a separate src/api/timetable.ts module to stay consistent with the
codebase's "api+composables together" pattern (useShifts.ts, useSections.ts).
