<!-- Provide a brief summary of your changes -->
## Motivation and Context
<!-- Why is this change needed? What problem does it solve? -->
The Repository field in ServerJSON was not properly omitting empty
values
when marshaling to JSON. Even when a server had no repository
configured,
the JSON would include `"repository": {"url": "", "source": ""}` due to:
1. Repository struct fields (URL, Source) lacking omitempty tags
2. Repository being a value type instead of pointer in ServerJSON
This caused validation warnings for servers without repository URLs.
Changes:
- Add omitempty tags to Repository.URL and Repository.Source fields
- Change ServerJSON.Repository from model.Repository to
*model.Repository
- Update validateRepository to handle nil pointers
- Update all code creating Repository instances to use pointers
Now, servers without repository information correctly omit the field
entirely from JSON output, eliminating spurious validation warnings.
