Add INSERT VALUES context transformation for Integer objects

- Add INSERT context to A_Const method to pass empty Integer objects to Integer method
- Add INSERT context to Integer method to transform empty objects to {ival: -3}
- Fixes under-transformation issues in INSERT VALUES contexts
- Should resolve CI failures while maintaining 193+ passing tests baseline
