- Added idempotency_key parameter to settlement bill adjustment and payment endpoints to prevent duplicate operations
- Fixed player rebate profile updates to preserve existing values when only one field is modified
- Moved wallet player validation earlier in AdminPlayerStoreController to prevent unnecessary processing
- Enhanced extra rebate calculation to include 'in_bill' and 'settled' statuses in AgentP
