P17: CommonCodeController → FastEndpoints (AllEndpoints.cs)

- Migrate CommonCodeController to 6 FastEndpoints
- GetAllActive, GetByGroup, GetGroups, GetByGroupAndValue, Upsert, Delete
- Backup original controller as .bak
- All endpoints require Bearer token auth
- Validation rules enforced on Upsert (no spaces in group/value)
