fix(tests): resolve CI failures in lint and integration tests

- Fix code formatting in tests/integration/contract_test.go using gofmt
- Fix OpenAPI validator tests to use correct health endpoint path (/health instead of /api/v1/health)
- Resolves lint job failure due to formatting issues
- Eliminates OpenAPI validator warnings about missing /api/v1/health spec
