printedparts stage 14: retire/restore in the UI, dashless item codes

Retire button with confirmation on the detail page (item leaves the
storefront and the kiosk rejects its code; ledger history and label
survive), Restore on retired items, and an Include-retired list toggle
with a badge. Restore is its own permission-gated POST - the generic
update still cannot flip isactive. New codes mint as WJRP0042 style
without the dash; existing codes are immutable bin labels and keep
their form.

+Field feedback stage: the soft-delete endpoint existed with no button, and
+the site wanted `WJRP0042`, not `WJRP-0042`.
+1. Detail gains Retire (confirm dialog; item leaves the storefront and the
+   kiosk 404s its code, history and label intact) and Restore; the list
+   gains an Include-retired toggle (`?active=false`) with a Retired badge.
+   Restore is its own POST gated by printedparts.delete - PUT deliberately
+   cannot flip isactive.
+2. Minting drops the dash: `f'{prefix}{id:04d}'`. Existing items keep their
+   codes - itemcode is an immutable label once printed on a bin.
