fix(studio): show all offers in the imported-furniture tree

The organize-imports route defaulted to a 500-item limit, silently
hiding offers beyond the first batch of imported pages.  Remove the
effective cap (limit now means 'all', guarded only by a 50k lint cap)
so every offer already sitting in the import tree is returned and
grouped.
