feat: member portal Sprint 4 — Events + RSVP

- Event + EventRsvp models + migration (RsvpStatus enum: GOING/MAYBE/NOT_GOING)
- EventsModule: admin CRUD (create/update/delete/publish) + RSVP list
- GET /my/events + POST /my/events/:id/rsvp in MyController/MyService
- Admin BFF routes: GET/POST /api/admin/events, PATCH/DELETE /api/admin/events/[id]
- Member BFF routes: GET /api/my/events, POST /api/my/events/[id]/rsvp
- /my/events page: upcoming/past split, RSVP button (client component, optimistic)
- Register DigestModule, OrgModule, ThreadsModule, EventsModule in AppModule
- Add EVENT_CREATED/DELETED/UPDATED and DIGEST_SENT to AuditAction
