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
Introduce PocketBase workflow support, migration tooling, server APIs and documentation. Adds a set of PocketBase collection JSONs (order_items, order_items_v2, collection_pool, delivery_notes, delivery_note_items, repairs) and a large import manifest for workflow collections; includes docs describing MCP/API layer, migration audit, order-item schema and rollout plans. Adds server-side agent/MCP endpoints and services (api/mcp, api/v1/orders, collection-pool, order-items status, health) plus helper modules (pocketbase-admin, orders-service, order-item-status, agent-auth) and a migration script to create order_items_v2/collection_pool. UI: new pages for collection-pool, delivery-notes, repairs and several updates to orders/quotes pages, sidebar, tooltip and pb helpers/types. Also updates package.json (migration script and related changes) and global styles. Required env vars and suggested migration command are documented (e.g. NEXT_PUBLIC_POCKETBASE_URL, PB_ADMIN_EMAIL, PB_ADMIN_PASSWORD, ORDER_ITEMS_COLLECTION; run npm run pb:migrate:orders-v2).
