feat: Phase 9 — Offline Detection, API Key Auth, Agent Self-Update

Browse Source 
Offline Detection (9.1):
- AgentOfflineDetectorService: BackgroundService, prüft alle 60s
  ob Agents seit >5 min kein Heartbeat hatten → Status=Offline
- IServiceScopeFactory für korrektes Scoped-DI im Singleton
- SignalR-Push AgentStatusChanged bei jeder Offline-Markierung

API Key Auth (9.2):
- ApiKeyMiddleware: prüft X-Api-Key Header gegen Security:ApiKey Config
- Deaktiviert wenn ApiKey leer (Dev-Modus), Swagger/hubs bypassed
- Frontend: getApiKey() aus localStorage, automatisch in allen Requests
- Settings-Modal in Sidebar: API-Key eingeben + maskiert anzeigen

Agent Self-Update (9.3):
- internal/updater/updater.go: CheckForUpdate() + Update()
  Download, SHA256-Verify, Windows Batch-Neustart / Linux Shell-Neustart
- AgentReleasesController: GET /api/v1/agent/releases/latest,
  GET /api/v1/agent/releases/download/{platform}
- AgentReleaseOptions: LatestVersion, ReleasePath, Checksum in appsettings
- executeCommand() erhält cfg *Config statt agentID string
  (für ServerAddress-Ableitung im UpdateAgent-Case)
