fix(tests): resolve EntriesIsolationIntegrationTest failures with test-specific DB config

- Added `TestExposedConfiguration` to connect Exposed with Spring `DataSource` in the `test` profile.
- Downgraded `springdoc` version from `3.0.0` to `2.8.9` for Spring Boot 3.x compatibility.
- Applied `@ActiveProfiles("test")` to `EntriesIsolationIntegrationTest`.
- Updated roadmap documentation to reflect bugfix and test success.
