Add manufacturer catalog, category/manufacturer library management, and built-in cable flag

Normalizes manufacturer as a shared catalog entity (like device categories)
instead of free text on each device, giving the admin duplicate-detection
nudge a reliable signal. Adds full CRUD (including Admin direct-publish,
bypassing the submission queue) for categories, manufacturers, port types,
and cable types, plus a Categories & Manufacturers library modal and a
browse-by-manufacturer/search view in the device palette. Adds
Port.builtInCable so a captive/permanently-attached cable (a keyboard's USB
lead, a budget AVR's power cord) can be flagged and excluded from the BOM.
