Add real-time UI updates after Traefik version check

Dispatch ProxyStatusChangedUI event after version check completes so the UI updates in real-time without requiring page refresh.

Changes:
- Add ProxyStatusChangedUI::dispatch() at all exit points in CheckTraefikVersionForServerJob
- Ensures UI refreshes automatically via WebSocket when version check completes
- Works for all scenarios: version detected, using latest tag, outdated version, up-to-date

User experience:
- User restarts proxy
- Warning clears automatically in real-time (no refresh needed)
- Leverages existing WebSocket infrastructure
