Add public REST API, anti-abuse protections, radio/GitHub cron jobs

Phase A — Public REST API (was the biggest gap). 20 JSON endpoints under
/api mirroring AtomCMS: users/[username], online(+/count), me, articles
(+/[slug]), photos, home, staff, teams, leaderboard, shop(+/categories),
values(+/categories), settings, radio/{config,now-playing,listeners,
shouts}. Shared src/lib/api.ts (apiJson — BigInt-safe + CORS, pagination).
Read-only, fail-soft, and field-safe (never exposes password/auth_ticket/
2FA secrets/mail).

Phase B — Anti-abuse on registration: CAPTCHA (Cloudflare Turnstile /
Google reCAPTCHA, settings-driven, widget rendered on the register page),
VPN/proxy detection (proxycheck.io / IPQualityScore via /admin/vpn
settings), and max-accounts-per-IP. All fail-open when unconfigured.
src/lib/services/{captcha,ip-lookup}.ts.

Phase C — jobs-worker cron suite: radio-record-songs (30s, logs track
changes to radio_song_plays), radio-auto-dj (rotates radio_auto_dj_playlist
when no live DJ), github-update-check (hourly, sets update_available).
Shared src/lib/services/radio.ts (now-playing/listeners parsing).

Verified live (prod, amx_test): /api/* return real JSON (leaderboard 6
users, settings carry no secrets, user endpoint hides password). tsc 0,
vitest 49/49, next build 0 (20 new API routes).
