feat: implement host dashboard

Add Host Dashboard for event and guest management, accessible at /host.

Backend — new /api/v1/host/* endpoints (RequireHost auth):
- GET  /host/event                    → event name + lock/release state
- POST /host/event/close|open         → lock or unlock uploads; SSE broadcast
- POST /host/gallery/release          → set release timestamp, enqueue export jobs
- GET  /host/users                    → all guests with upload count & bytes
- POST /host/users/{id}/ban           → ban with optional upload-hide choice
- POST /host/users/{id}/unban         → lift ban
- PATCH /host/users/{id}/role         → promote guest→host or demote host→guest
- DELETE /host/upload/{id}            → host-level soft-delete + SSE
- DELETE /host/comment/{id}           → host-level soft-delete

Frontend — /host page:
- Event controls: lock/unlock toggle and release-gallery button with status badges
- Guest table: display name, role badge, upload count, storage used
- Ban flow: modal asking whether to keep or hide the user's uploads
- Promote/demote buttons respecting caller role (host can promote guests; admin can demote hosts)
- auth.ts: getRole() decodes JWT payload client-side to gate the route
