Add comprehensive documentation and refactor tests for database consolidation - Introduced `copilot-instructions.md` for AI coding agent guidance on project structure and development workflows. - Created `DATABASE_CONSOLIDATION_SUMMARY.md` detailing the purpose and implementation of database unification across tests. - Added `TEST_DATABASE_REFERENCE.md` for quick reference on database usage in tests. - Implemented `DataTypes.ts` to define TSDataType enum and utility function for data type retrieval. - Refactored `TableModelDataTypes.test.ts` to consolidate table model tests under a single database, ensuring resource efficiency and clarity. - Updated all relevant test files to use unified database names and added cleanup logic to maintain test integrity.
