Three coupled shop-floor corrections:
1. Job display rename: WH/JOB/00011 -> Work Order # 00011
via display_name compute (name stays stable for DB refs)
2. Quantity gate on button_finish: refuses if qty_at_step > 0
AND there is a downstream pending/ready step (last step exempt)
3. Partial-qty UX: new action_complete_one_to_next per-row button
for streaming flow; auto-move shim on Finish for 1-of-1; Move
wizard unchanged (already has zero-qty + over-qty guards)
Spec covers architecture, state transitions, test plan,
files-touched matrix, and explicit Out of Scope (qty_done auto-tick,
per-step scrap, cert PDF display).
