This commit enhances the `invoice`, `taxrecord`, `orderitem`, `purchaseorder`, `shipment`, and `salesorder` schemas by introducing new rollup configurations for various states and values. It adds methods for aggregating statistics and historical data using `aggregateRollups` and `aggregateRollupsHistory`, improving data analysis capabilities across financial and inventory records. The new rollups include counts and sums for different transaction types and states, facilitating better reporting and insights into the application's financial and inventory management.
- Renamed 'vendor' and 'client' fields to 'from' and 'to' for better semantic understanding.
- Added 'acknowledgedAt' field to track acknowledgment date of invoices.
- Added new schemas for invoice order items and shipments to support detailed invoice management.
- Updated the main invoice schema to include references to order items and shipments.
- Implemented a recalculation method for invoice totals, including amounts with and without tax.
- Enhanced rollup configurations to provide more detailed statistics on invoice states.
