dashboard: route CRUD, source-aware service controls, XSS fix

- Add inline route management (+ route / x) per service in dashboard
- Expose service source (config vs api) in API response
- Only show service delete button for API-created services
- Pre-fill route port with service target_port
- Fix XSS in route path onclick handlers
- Skip renderServices refresh while route form is open (editingRoute guard)
