Fix GetLocale test to match OpenAPI specification

[Copilot]

The GetLocale test was incorrectly expecting the response to be wrapped in a "data" field, causing test failures:

Error: json: cannot unmarshal string into Go value of type oapi.Locale

Changes

• services/nexus/internal/http/controllers/v1/locales_test.go: Fixed test to expect Locale object directly instead of wrapped in a "data" field

The OpenAPI specification at services/nexus/oapi/resources.yml defines the GetLocale endpoint response as:

responses:
  '200':
    description: Locale retrieved successfully
    content:
      application/json:
        schema:
          $ref: '#/components/schemas/Locale'

This clearly indicates the response should be a Locale object directly, not wrapped in a data field. The test has been updated to align with this specification.

Testing

• ✅ All locale tests passing (TestGetLocale/get_by_id, TestGetLocale/get_by_key, TestGetLocale/not_found)

• ✅ Code compiles successfully

• ✅ CodeQL security check passed

• Fixes Locale tests are failing #86

the locale OAPI should not be returned in a data object. Please update the OpenAPI specs if needed.

Fixed in 06c7f04. Reverted the controller to return the locale directly (matching the OpenAPI spec) and updated the test to expect the Locale object without the "data" wrapper.
