feat(events): add mana-events service + public RSVP flow (Phase 1b)

New Hono+Bun service at services/mana-events on port 3065 with two
schemas in mana_platform: events_published (snapshots) and public_rsvps
(unauthenticated responses), plus a per-token hourly rate-limit bucket.

- Host endpoints (JWT) for publish/update/unpublish/list-rsvps
- Public endpoints for snapshot fetch + RSVP upsert with rate limiting
- New /rsvp/[token] page outside the auth gate, SSR-loads the snapshot
- Client store wires publishEvent/unpublishEvent to the server, syncs
  snapshot updates after edits, and deletes the snapshot on event delete
- DetailView polls GET /events/:id/rsvps every 30s while open and lets
  hosts import a public response into their local guest list
- generate-env, setup-databases.sh, .env.development, hooks.server.ts,
  package.json wired for local dev
