fix: Replace deprecated @MockBean with @MockitoBean

- Updated all 13 test files to use @MockitoBean from Spring 6.x
- Changed import from org.springframework.boot.test.mock.mockito.MockBean
  to org.springframework.test.context.bean.override.mockito.MockitoBean
- Fixed JWT deprecation warnings in OAuth2TestUtils by updating to newer JJWT API
- Removed deprecated SignatureAlgorithm usage
- Build now compiles without any deprecation warnings
