Subject: [PATCH] Remove quantity option from add/edit forms

Each discrete item (pre-roll, edible, etc.) is now always one
physical unit with its own asset ID. The quantity field is gone
from both add and edit flows, countOriginal is hardcoded to 1,
and price is just "Price" instead of "Price per unit."
