feat(wallet): add manual credit wallet charge functionality and update Protobuf definitions

- Introduced ManualCreditWalletCharge enum value to TransactionType for clarity.
- Added AdminManualCreditCharge and GetManualCreditCharges RPC methods in UserWalletService for handling manual credit charges by admin.
- Created corresponding request and response messages for manual credit charge operations in Protobuf.
- Updated Protobuf project version to reflect the addition of new features.
