Standardize ZXDB UI; add SSR search/tables

Unify the look and feel of all /zxdb pages and minimize client pop-in.

- Make all /zxdb pages full-width to match /explorer
- Convert Languages, Genres, Machine Types, and Labels lists to
  Bootstrap tables with table-striped and table-hover inside
  table-responsive wrappers
- Replace raw FK IDs with linked names via SSR repository joins
- Add scoped search boxes on detail pages (labels, genres, languages,
  machine types) with SSR filtering and pagination that preserves q/tab
- Keep explorer results consistent: show Machine/Language names with
  links, no client lookups required

This improves consistency, readability, and first paint stability across
the ZXDB section while keeping navigation fast and discoverable.
