feat(03-03): implement write API surface — create/edit/delete + sync-status + writable-calendars
- POST /create: validates with zod, checks calendar ownership (D-03/T-03-06), enqueues pending outbox row, returns 202 with uid
- PATCH /:uid/edit: looks up event, checks ownership, enqueues update row; uses db.transaction for edit-as-move calendar pair (D-04)
- DELETE /:uid: looks up event, checks ownership, enqueues delete row with server-side etag (T-03-10)
- GET /sync-status: returns outbox status scoped to currentUser only (T-03-07/D-09)
- GET /writable-calendars: returns own personal + shared calendars, never other member's personal (D-03/T-03-11)
- Auth via dev-bypass (c.get('user')) + getAuth(c) fallback; 401 if neither
- No tsdav import — broker boundary enforced (D-12)
- All 69 events tests GREEN; tsc --noEmit clean
