Add comprehensive test coverage for DatabaseRuleConfigurationCheckEngine
(#36929)
* Move FirebirdSystemDatabaseTest
* Add comprehensive test coverage for DatabaseRuleConfigurationCheckEngine
- Create DatabaseRuleConfigurationCheckEngineTest with 5 core test cases
- Test null checker scenario (TODO branch handling)
- Test empty data sources and tables scenario
- Test missing data sources exception handling
- Test logic data sources handling (should not throw exception)
- Test duplicated table names exception handling
- Use AutoMockExtension and StaticMockSettings for clean mock management
- Apply inline variable declarations for concise test code
- Use Hamcrest assertions for readable validation
- Achieve 100% test coverage for DatabaseRuleConfigurationCheckEngine
