fix: complete Phase 3 - replace remaining universal_json_load calls in code_funcs.py

- Line 498: Changed from universal_json_load to use _parser from FILL_BILL_TYPE tuple
- Line 856: Updated GROUPER_BREAKOUT call to unpack tuple and use grouper_parser
- Removed unused GROUPER_QUESTIONS variable (fields now in INSTRUCTION function for caching)
- All universal_json_load calls in code_funcs.py have been replaced
- Phase 3 is now 100% complete
