fix(core): Fix mode negation and core mode

[elizabethhealy]

Proposed Changes

• There was an issue where services started in core mode were registered but not starting. It looks like they were registered with the namespace as the mode instead of the specified mode from the config. This PR corrects this and adds test checks to ensure services registered are also enabled.
• Namespaces will be registered with the mode that caused them to be included -- if all is in the list then the namespaces will have mode all, if core,ers is the mode then policy will have mode core and entityresolution will have mode entityresolution ...

Checklist

• I have added or updated unit tests
• I have added or updated integration tests (if appropriate)
• I have added or updated documentation

Code Review

This pull request addresses a bug where services were not being correctly enabled in 'core' mode because they were registered with their namespace as the mode instead of the specified mode from the configuration. The fix in service/pkg/serviceregistry/serviceregistry.go correctly identifies and uses the intended mode for service registration, which resolves the issue. The accompanying test updates in service/pkg/server/services_test.go are a good addition to verify this fix. However, I've noticed a small issue in the new test logic where a function call intended for assertion is missing the actual assertion, rendering that part of the test ineffective. My feedback includes suggestions to correct this in the tests.
