refactor: extract transaction creation and account syncing to actions

- Introduce CreateRecordTransactionsAction to handle transaction creation for any model
- Introduce SyncAccountsAction to encapsulate account synchronization logic
- Refactor CreateSaleAction to use new actions and handle full sale creation flow
- Simplify CreateExpense and CreateSale pages by delegating to actions
- Ensure proper transaction handling with database rollback on failure
