feat: Michess – Initiales Setup auf Basis von chessu

- Rebranding: chessu → Michess (Header, Footer, Metadata, Session-Cookie)
- Stockfish KI-Integration: 6 Schwierigkeitsgrade (Anfänger bis Meister)
- Admin-Panel: Nutzerverwaltung, Sperren/Entsperren, Git-Pull-Update
- Freundessystem: Anfragen, Freundesliste, Nutzersuche
- DB-Schema: role, banned, friend_request, friendship Tabellen
- Docker: NAS-optimiertes docker-compose.yml mit PostgreSQL Healthcheck
- Stockfish binary via apk im Alpine-Image installiert
- .env.example für einfaches Deployment
- scripts/update.sh für manuelles NAS-Update
- Brain.md + Plan.md als Projekt-Gedächtnis
