refactor: UI improvements and code cleanup

Frontend:
- DetectionsList: Simplify columns, improve truncation and display for IPs, hosts, bot info
- IncidentsView: Replace metric cards with compact stat cards (unique IPs, known bots, ML anomalies, threat levels)
- InvestigationView: Add section navigation anchors, reorganize layout with proper IDs
- ThreatIntelView: Add navigation links to investigation pages, add comment column, improve table layout

Backend:
- Various route and model adjustments
- Configuration updates
