Matches the backend: subcategory is no longer a required field in the
import modal (defaults to none/0 instead of blocking submission), and
the Category dropdown now comes from GET gettenantcategories (what
this tenant's own products actually use) instead of the global
categories list, which was missing categoryid 2 despite it being the
category tenant 1135 actually needs.
