ui(product): restructure product specs tab with sections and fix pricing tab gap

- Product specs tab: group fields into bordered sections (اطلاعات پایه, وزن و واحد, تنظیمات نمایش)
- Visibility switches in a compact panel with divider lines
- Weight/unit/inventory fields in same grid row
- Pricing tab: wrap all content in flex-col gap-4
- Remove unnecessary product-editor-panel border from non-melted pricing block
