printedparts stage 3: read API + list page (first visible win)

GET /items (paginated, search across code/name/description/bin,
lowstock filter) and GET /items/<id> with recent transactions, both
open reads. printedpartsApi client, router file repointed at the
renamed views, PrintedItemsList with image thumbs and a red/green
quantity badge against the per-item threshold. Nav entry '3D Parts'
with a new 'box' Lucide icon mapping (the sidebar renders nothing for
unknown icon names - lab gotcha).
