Replaces the AI Insights section in order-sprint-process-modal with a
deterministic PocketBase-derived context block (last quote, last order,
last invoiced, stock). Same backend exposed as a popover trigger on
the orders detail page, replacing the existing AI-history ⓘ there.
Backend: new src/lib/server/order-item-context-service.ts +
GET /api/v1/order-items/[id]/context. Reuses pure helpers from
item-history-service (normaliseSkuForHistory, findBestDescriptionMatch,
aggregateSuppliers, computeCheapest).
UI: new <OrderItemContextPanel/> (inline expandable for the sprint
modal) and <OrderItemContextPopoverTrigger/> (ⓘ popover for orders
page). Apply = cost + supplier only; selling stays locked to the order.
