fix(money,orders): wage/gram-debt parity, atomic document confirm, expert edit, made-to-order, QA fixes

- Rial wage and gram-debt arithmetic matched to the reference; order corrections keep debt in sync
- Document confirm/un-confirm is a compare-and-swap (no double-applied cache under concurrency)
- Settlement document and expert inputs validated (400 instead of 500)
- Expert: edit / activate-deactivate own customers, adjust raw weights only
- Made-to-order flow in the app, PreOrder.quantity migration
- Order grids: customer column, sort keys; panel select search; pre-order quantity save
- Rebuilt release artifacts
