Cam Proudlock 11c8d79ba4 Add the printedparts plugin: 3D-printed parts storefront and kiosk
Catalog with photos and append-only print-file revisions, a stock
ledger attributing every take/restock/adjust to a badge-resolved
employee, a touch kiosk (scan bin, scan badge, keypad quantity) with a
deliberately open decrement-only take endpoint, 1x0.5in CODE128 bin
labels, low-stock email alerts to selected users, roles, or addresses,
and stock/consumption/by-person reports with a cache-vs-ledger
reconcile. Ships disabled; enable per site. Contract 0.13.0 adds the
mailer and the User/Role models to the plugin surface.

"""Badge resolution for the printedparts plugin.
Same input contract as the USB plugin (deliberately copied, not imported -
cross-plugin imports break the shopdb.api-only contract):
- all digits -> an SSO typed or scanned directly
- 0<digits>BZ -> a physical badge wrapping a PayNo (keyboard-wedge
scanners emit this shape)
- anything else -> unresolvable
Names come from the employees plugin's self-hosted directory, looked up by
SSO. The directory carries no PayNo column, so PayNo badges resolve only when
the wrapped digits are themselves the SSO (true at sites whose badges encode
the SSO); otherwise they fall to the unknown-badge policy.
Policy (Setting printedparts_unknown_badge): 'deny' (default) rejects a badge
with no directory match; 'allow' records the SSO with an empty name.
