feat: remove Administration workspace — keep only Verwaltung + Suche

- Delete all ops page components (ReviewQueue, AIMonitoring, Governance,
  SourceMonitoring, ActivityTimeline, SignalPipeline)
- Remove OPERATIONS workspace from AppShell config, nav order, path detection
- Remove all /ops/* routes from App.tsx
- Remove WorkspaceType.OPERATIONS from allowedWorkspaces in authService,
  sessionStore, permissions
- Keep MarketIntelligence page (already moved to /supply/market-intelligence)
