fix: update PG13-to-PG14 transformer to use runtime schemas

- Fix A_Const transformation direction (PG13→PG14 instead of PG14→PG13)
- Add FuncCall funcformat default value handling
- Import and use runtime schemas for field transformation guidance
- Add SelectStmt sortClause handling (was missing, only had orderClause)
- Add TypeCast method to ensure proper TypeName transformation
- Add ColumnDef and Constraint methods for missing field handling
- Fix TypeName to add required typemod defaults
- Improve recursive transformation handling across nested AST structures

Tests passing: 98/258 (significant improvement from initial state)
Key fixes: A_Const val structure, FuncCall funcformat, sortClause processing
