perf: optimize CMS queries, caching, and asset delivery

Database:
- Add missing indexes (users.credits, users_currency(type,amount),
  users_settings.respects_received, camera_web.timestamp,
  messenger_offline.user_id) via migrations 0020/0021
- Use partial .select() everywhere instead of SELECT * (tickets, users,
  rooms, audit logs, catalog tree, polls, radio, password reset)
- Add queryPrepared/queryPreparedOne (server-side prepared statements)
  and switch the login check to a prepared statement; drop dead
  cache options from the pool config
- Raise total_users/total_rooms COUNT(*) cache TTL to 5m

Caching:
- Consolidate the three cache helpers (cached, redisCache, cachedQuery)
  into a single memory-first implementation backed by Redis
- invalidateKey now clears the in-process cache as well as Redis
- Cache homepage sections, news list, and leaderboard tabs; share one
  news_list cache key between homepage and news archive
- siteSettings: in-process cache with TTL so repeated getters no longer
  pay a Redis round-trip per call
- Share a 10s poll cache across all radio SSE connections
- Normalize timestamps after cache reads (Redis JSON round-trip)

Assets:
- Enable AVIF/WebP via images.formats and remove unoptimized from news
  covers and the homepage hero (149KB jpg) with proper sizes/priority
- Support ?format=webp|avif|png in the /imaging proxy via sharp

Other:
- Fix pnpm supply-chain minimumReleaseAge failures by excluding the
  freshly-published packages (next 16.3.1, hookform resolvers 5.8.0,
  resend 6.20.0)
- Remove unused before/after fields from housekeeping AuditEntry
