- Fixed schema isolation handling in Exposed by switching table creation to JDBC and explicitly setting `search_path` in PostgreSQL.
- Removed redundant `runBlocking` calls, unused variables, and IDE warnings in the test.
- Added `JwtDecoder` mock in `@TestConfiguration` to prevent application context loading errors.
- Verified that writes in one tenant schema are no longer visible in another.
chore(config): add `application-test.yaml` for better test environment setup
- Configured H2 as an in-memory database for tests.
- Disabled Flyway and Consul to avoid unnecessary dependencies during testing.
