Add payable filter to sales invoices and enhance invoice status handling

- Introduced a new `payable` filter in the `ListSalesInvoicesFilters` and `ListSalesInvoicesQuery` types to allow querying of invoices based on their payable status.
- Updated the `SalesInvoicesRepository` to incorporate logic for filtering invoices that are payable, checking both status and balance.
- Enhanced the `SalesInvoicesService` to support the new `payable` filter in query handling.
- Modified the `SalesInvoiceDto` to include the `payable` property for better API response representation.
- Added unit tests to validate the new filter functionality and ensure proper handling of invoice statuses during updates.
- Updated e2e tests to cover scenarios involving the new payable filter and status transitions for invoices.
