feat: nettoyage menu + suppression modules inexistants + log viewer

- Sidebar : retrait des liens files, logs, services (non implémentés)
- Migration 001 : suppression des inserts files/logs/services
- Migration 002 : DELETE des modules inexistants en DB existante
- logbuffer : ring buffer mémoire branché sur log.SetOutput
- GET /api/settings/logs : retourne les 300 dernières lignes de log
- Settings : onglet Logs avec auto-refresh (5s/10s/30s/60s/désactivé, défaut 10s)
