patrickandClaude Sonnet 5 edc05d4d1e fix(PROJ-11): clear the remaining QA backlog (BUG-5/6/9/10/13/14/15/16/17/21/22)
Every previously-reported bug from the three QA rounds is now addressed
(BUG-11 and BUG-15 mitigated rather than fully solved — see spec for
why). Verified end-to-end on talkhub/matrix after each change.

Security:
- BUG-21: @fastify/helmet registered, CORS origin allowlist (APP_BASE_URL
  + localhost:5173) replaces `origin: true`. Verified: own origin gets
  CORS + HSTS/nosniff/X-Frame-Options headers, foreign origins get none.
- BUG-13: GET /api/teams only returns matrixRoomId for teams the
  requester actually belongs to (was leaking every team's room id to
  any org member). Verified with/without team membership.
- BUG-14: leftJoin now filters scope='team'; new partial unique index
  chat_rooms_team_id_team_scope_unique enforces one room per team at
  the DB level, not just in the query (migration 0002).

Reliability:
- BUG-5: use-team-chat.ts's setup poll now backs off exponentially
  (5s->60s) instead of a fixed 15s; SyncState.Error stops the client
  and reconnects with backoff instead of letting matrix-js-sdk retry
  against Synapse forever.
- BUG-6: one-off backfill script (src/scripts/backfill-history-visibility.ts)
  sets history_visibility=shared on rooms created before that fix;
  run against talkhub/matrix.
- BUG-9: route rate limit on GET /api/chat/room, unified 404 for
  nonexistent-team vs not-a-member (was a cross-org existence oracle),
  LRU-correct eviction order in matrix-token-cache.ts, scroll position
  preserved on "load older messages", and eslint.config.js added (lint
  never ran on this feature before — flat config was simply missing).
- BUG-15 (mitigated): a small module-level credential cache in
  lib/matrix.ts lets useTeamChat and useTeamUnreadCounts share one
  fetched token instead of each hitting POST /api/chat/token
  independently. Reduces but doesn't eliminate rate-limit risk under
  rapid team switching (no in-flight dedup between the two hooks).
- BUG-16: refreshCounts() checks `cancelled` before setCounts.
- BUG-17: use-team-chat.ts uses getRoomUnreadNotificationCount()
  instead of the deprecated getUnreadNotificationCount(); left
  unchanged in use-team-unread-counts.ts on purpose, since importing
  NotificationCountType there would undo BUG-11's bundle-splitting fix.

Cleanup:
- BUG-10: new POST /api/chat/logout invalidates the cached token and
  calls Synapse's logout_all admin endpoint; frontend calls it
  best-effort on logout and clears its own credential cache.
- BUG-22: trim() on displayName construction (trailing space with an
  empty last name); the reported trailing-dot localpart is moot after
  BUG-20 since localparts are random now, not name-derived.
