Fix ZXDB pagination counters and navigation

Implement URL-driven pagination and correct total counts across ZXDB:
- Root /zxdb: SSR reads ?page; client syncs to SSR; Prev/Next as Links.
- Sub-index pages (genres, languages, machinetypes): parse ?page on server; use SSR props in clients; Prev/Next via Links.
- Labels browse (/zxdb/labels): dynamic SSR, reads ?q & ?page; typed count(*); client syncs to SSR; Prev/Next preserve q.
- Label detail (/zxdb/labels/[id]): tab-aware Prev/Next Links; counters from server.
- Repo: replace raw counts with typed Drizzle count(*) for reliable totals.
