feat(timetable): observers — engagement denorm/guard + performance version bump

Browse Source 
ArtistEngagementObserver:
- creating: auto-fills organisation_id from parent Artist (RFC v0.2 D10
  denormalisation), asserts artist.organisation_id == event.organisation_id;
  cross-tenant linkage throws CrossTenantEngagementException (extends
  DomainException, included in this commit).
- saving: no-op marker reserved for Session 2 state-machine validation.
- deleted: cascades soft-delete to Performance children, hard-deletes
  AdvanceSection children. AdvanceSubmission rows are immutable per
  RFC §5.4 and remain attached.

PerformanceObserver:
- saving: increments version by 1 on UPDATE only (D14 optimistic lock).
  MoveTimetablePerformanceRequest in Session 2 uses this for concurrent-
  edit detection.

Both observers registered in AppServiceProvider::boot.
