feat: add TenantLedger model and query generation
- Introduced TenantLedger model with fields for managing tenant transactions, including ID, TenantID, UserID, OrderID, transaction Type, Amount, and balance details. - Implemented CRUD operations for TenantLedger with methods for Create, Update, Delete, and Reload. - Generated query methods for TenantLedger to facilitate database interactions, including filtering, pagination, and aggregation functions. - Established relationships with Order model for foreign key references.
