This commit overhauls the order management system to use item-level status tracking instead of a single order-level status:
- Remove deprecated `orders.status` field and add `invoiced` and quote match audit fields
- Add `isOrderComplete` utility with tests to validate fully delivered orders
- Add purchase order PDF rendering support and tooling
- Add geo coordinate fields for companies/customers with map link UI
- Add REST management APIs for customers, companies, and suppliers
- Update customer/company services to use relation fields instead of free text
- Add status pill and tab filter components for item status visualization
- Add quote-to-order matching logic and unit tests
- Update all pages, components, and tests to match the new schema
- Include all required PocketBase migrations and schema updates
