fix: improve output of zot verify

[andaaron]

See #2744, there are 2 updates:

1. Silence the usage output in case of config verification errors
2. Wrap the error details in all of the zot configuration errors so they are propagated and shown in stdout for zot verify We also need to keep logging those message to the zot logs file since the same logic is called in the zot serve use case.
