Add lifecycle test validation for Config default values

Add checkResourcesInDesiredState() function to verify that the default
health probe port (8175) is correctly applied to bpfman and metrics
proxy DaemonSets when not explicitly set in the Config spec.

This test ensures the default value handling introduced in the API
standards compliance changes works correctly at runtime.
