ZXDB: Releases browser filters, schema lists, and fixes

- UI: Add /zxdb hub cards for Entries and Releases; implement Releases browser
  with URL‑synced filters (q, year, sort, DL language/machine, file/scheme/source/case, demo)
  and a paginated table (Entry ID, Title, Release #, Year).
- API: Add GET /api/zxdb/releases/search (Zod‑validated, Node runtime) supporting
  title, year, sort, and downloads‑based filters; return paged JSON.
- Repo: Rewrite searchReleases to Drizzle QB; correct ORDER BY on releases.release_year;
  implement EXISTS on downloads using explicit "from downloads as d"; return JSON‑safe rows.
- Schema: Align Drizzle models with ZXDB for releases/downloads; add lookups
  availabletypes, currencies, roletypes, and roles relation.
- API (lookups): Add GET /api/zxdb/{availabletypes,currencies,roletypes} for dropdowns.
- Stability: JSON‑clone SSR payloads before passing to Client Components to avoid
  RowDataPacket serialization errors.
