fix: close TOCTOU race + missing checks in tier limits, add AI rate limits, patch CVEs (v0.60.0)

Security audit fixes (see SECURITY_AUDIT.md):
- lib/tiers.ts: checkAndIncrementTierLimit's recipe/storage branches did a
  live count/sum check with no lock tying it to the later write, so two
  concurrent requests near the cap could both pass and both write past the
  limit. Added checkTierLimitInTransaction — holds a per-user Postgres
  advisory lock for the duration of the caller's transaction, so the check
  and the write are atomic together. Applied to every recipe/storage write
  path (recipes create/update, fork, rate, avatar, and 7 AI recipe-creation
  routes).
- Adversarial re-verification of that fix caught a bigger gap in the same
  area: four AI routes (photo import, idea generation, batch-cook,
  translate-to-new-draft) had no recipe-limit check at all. Fixed.
- Added missing per-user rate limits to 5 AI endpoints (adapt, drinks,
  pairings, translate, variations) that had none, unlike their siblings.
- search page now checks for a session server-side, matching every other
  page under (app)/ — defense in depth; the underlying API was already
  public by design and proxy.ts already blocked unauthenticated requests.
- admin/settings route now uses the shared requireAdmin instead of a local
  duplicate.
- Documented two admin support-ticket endpoints missing from the OpenAPI
  spec; verified full route/OpenAPI parity otherwise.
- Bumped drizzle-orm to fix a SQL-identifier-escaping CVE, and overrode two
  transitive deps (esbuild, postcss) with known CVEs. pnpm audit is clean.
