Summary
A new Restocking tab where users set a budget via slider and get demand-forecast-driven restock recommendations that fit within it. Placing an order surfaces it in the Orders tab with a computed delivery lead time.
How it works
Recommendation algorithm (server/main.py): greedy budget fill. Items are scored by trend_weight * 1000 + demand_growth (increasing=3, stable=2, decreasing=1), sorted descending, then added until budget is exhausted. Unit costs come from inventory.json where available, with a fallback table for demand SKUs that don't exist there (8 of 9).
Lead time: the slowest item sets the pace for the whole shipment. Increasing-trend items ship in 7 days, stable in 14, decreasing in 21, so a mixed order gets max() of its items' lead times.
UI flow: drag slider, recommendations table live-updates, click Place Order, success banner shows order number + lead time, switch to Orders tab, new "Submitted Restocking Orders" section appears above All Orders.

Tests
14/14 passed in test_restocking.py, 54/54 in full backend suite. Adversarial checks (zero/negative budget, invalid trend, idempotency, 5-way concurrent POSTs) all handled correctly.
