fix: multi-category checkboxes in admin + requires-delivery toggle

- Category selector replaced with checkboxes — items can now be
  assigned to multiple categories directly in admin (not just Square).
  Each category shows a "Square" label if it came from the Square
  assignment. Saves as categoriesOverride[] (array of category names).
- categoriesOverride takes precedence over old categoryOverride in the
  catalog route; old overrides still work as fallback.
- Requires-delivery toggle and custom rate fields were already in the
  code but needed container rebuild to appear — no logic change.
