Add JdbcSourceCoordinationStoreTest covering error handling, version mismatch, table creation, and TTL paths (34 test cases). Add jacocoTestCoverageVerification with minimum 0.90 ratio. Add docker-compose.yml with PostgreSQL 16 and MySQL 8.4 for integration tests. Replace FQCN usages with imports.

Add test cases for table creation, MySQL duplicate index, non-constraint SQL exceptions, assigned-expired acquisition, null closedCount, and priority override branches. Raise JaCoCo minimum from 0.90 to 0.99. Replace remaining FQCN usages with imports in source and test files.
