Supporto Docker/Unraid: build, healthcheck, docs

Aggiunti Dockerfile multi-stage, .dockerignore e docker-compose.yml per deployment containerizzato (con healthcheck, volumi persistenti, limiti risorse). Script di build per Linux/Mac e Windows. In Program.cs aggiunto endpoint /health e health checks per orchestrazione. Documentazione estesa: guide Unraid, quickstart Docker, workflow Git/DevOps, best practices su sicurezza, backup, monitoring. Progetto ora pronto per deploy e gestione professionale in ambienti Docker/Unraid.
