1. Controller class names didn't preserve acronym capitalization
2. Missing __init__.py files prevented Python from importing modules
3. Missing JS files caused incomplete doctype structure

1. ✅ Correct 7 controller class names (preserve acronyms):
   - TDS Settings → TDSSettings
   - Production Plant AMB → ProductionPlantAMB
   - KPI Cost Breakdown → KPICostBreakdown
   - COA AMB2 → COAAMB2
   - Lote AMB → LoteAMB
   - RND Parent DocType → RNDParentDocType
   - Third Party API → ThirdPartyAPI

2. ✅ Add required __init__.py files for all doctype directories
3. ✅ Add missing JS files for complete doctype structure
4. ✅ Update JSON files for consistency

✅ All controllers import successfully
✅ Migration completes without 'Orphaned DocType' messages
✅ Clean migration output
✅ Ready for production deployment
