chore(analytics): Umami-Kern entfernen — Injection, Client-Lib, Auth-Hook, Container, DB

Erster Schritt der Umami-Komplett-Entfernung (Entscheidung: kein Web-Analytics):
- hooks.server.ts: injectUmamiAnalytics-Injection raus (stoppt Script-Load in der Unified-App)
- packages/shared-utils/analytics-server.ts: GELÖSCHT (Script-Injection-Util)
- packages/shared-utils/analytics.ts: zu No-op entkernt — window.umami/isUmamiAvailable
  raus, trackEvent no-op; alle 28 *Events-Aufrufer kompilieren weiter (senden nichts)
- packages/shared-auth/authService.ts: inline-Umami-trackAuth-Hook + Aufrufe raus
- infrastructure/docker-compose.gpu-box.yml: umami-Service (mana-mon-umami) raus
- docker/init-db: CREATE DATABASE umami + GRANT raus
- gelöscht: docs/ANALYTICS.md, scripts/mac-mini/setup-umami-db.sh, picture-landing .env.example

VERBLEIBEND (separat, größer): ~60 weitere Dateien — 7 Landing-Layout.astro
(eigene Script-Injection), website-blocks Analytics-Feature, Legal/Datenschutz,
i18n×5, Admin-UI, ~20 Docs. Teils produkt-/rechts-sensibel → in Wellen.
