fix: Code-Quality und Security-Verbesserungen

Security Fixes:
- Fix XSS vulnerability in orchestrator.html (escapeHtml für user input)
- Verbesserte Error-Handling: 4 bare except clauses mit spezifischen Exception-Typen

Code Quality:
- Logging für alle Exception-Handler hinzugefügt
- Timeout für Agent-Tasks von 300s auf 600s erhöht (10 Min)
- Bessere Kommentare für Exception-Handling

Performance:
- Wissensdatenbank aus Systemprompt entfernt
- Agents nutzen @READ_KNOWLEDGE für on-demand Zugriff
- Reduziert Prompt-Größe um ~15KB pro Task

UI Improvements (aus vorherigem Work):
- Tasks: Auto-Refresh Info statt Toggle
- Tasks: Status-Anzeigen statt manuelle Buttons
- Konsistentes Auto-Refresh (15s) wenn Tasks aktiv
