fix: show location (country, city, district) in product edit modal

- JSON endpoint now joins locations+categories+subcategories for full info
- Edit form shows location tags (country, city, district) at top
- Location hidden when adding new product (no location yet)
- All fields properly filled by fillEditForm on edit
- Category and subcategory side by side in edit form
