feat(auth): implement all 16 homepage/login/register review items

- add countArticles() (published-only, mirrors news-list) and warm total_articles
- localize homepage metadata; bind articleCount to both stats; unique photo alts
- drop duplicate news date and the mascot preload priorities
- extract shared AuthPageFrame/AuthUsersCards used by /login and /register
- login: localized noindex metadata, session redirect via safeRedirectPath,
  ?from passthrough from proxy, unified auth roster cache keys, registered notice
- register: localized metadata, session redirect to /me, unified cache keys
- add resend-verification flow on /verify with rate-limited non-enumerable action
- add safeRedirectPath() with unit tests
- register form: live requirements checklist + password mismatch guard
- login form: unverified state with resend-link CTA
- honour prefers-reduced-motion in TypewriterText
- add 6 translations across all 25 locales
