feat: add balance and ledger endpoints for tenant

- Implemented MyBalance and MyLedgerPage methods in the ledger service to retrieve current user balance and transaction history for a specified tenant.
- Added corresponding test cases for MyBalance and MyLedgerPage methods in the ledger test suite.
- Created DTOs for balance response and ledger items to structure the response data.
- Updated Swagger documentation to include new endpoints for retrieving tenant balance and ledgers.
- Added HTTP tests for the new endpoints to ensure proper functionality.
