Revert INSERT VALUES transformation to restore stable baseline

- Remove INSERT VALUES context logic from Integer method that caused over-transformation
- Restore 194 passing tests baseline (was 185 with regression)
- Fix CI parser-tests failures caused by widespread over-transformation
- Maintain conservative transformation approach for TypeName and DefineStmt contexts only
