Fix CamelAzureEventhubsITest flakiness

- Add explicit Event Hub entity config (eh1) so the emulator creates it
- Use log-based wait strategy instead of port-based to ensure emulator
  is fully ready before tests run
- Use acceptLicense() instead of env var
- Increase mock assertion wait time to 60s to allow for slow startup
