Restore 194 passing tests baseline by removing over-transforming INSERT VALUES logic

- Removed INSERT VALUES context condition from A_Const method that was causing regressions
- Removed INSERT VALUES transformation logic from Integer method that was over-transforming
- Maintains stable baseline of 194 passing tests (64 failed, 258 total)
- Ready for more conservative INSERT VALUES transformation approach
