feat: Fix CrowdSec re-enrollment and live log viewer WebSocket

- Add logging when console enrollment is silently skipped
- Add DELETE /admin/crowdsec/console/enrollment endpoint
- Add enhanced re-enrollment UI with CrowdSec Console link
- Fix WebSocket authentication by passing token in query params
- Change Live Log Viewer default mode to security logs
- Add error message display for failed WebSocket connections

Fixes silent enrollment idempotency bug and WebSocket
authentication issue causing disconnected log viewer.
