Subject: [PATCH] refactor: switch equipment_detail from CSR to SSR

- Updated equipment_detail view to load data from DB (SSR)
- Added select_related and prefetch_related for optimization
- Implemented can_manage permission check in view
- Removed loadEquipmentDetail() JavaScript API call
- Added breadcrumb navigation
- Kept action handlers (maintenance, transfer, write-off)
- Added department loading for transfer modal
- Now consistent with request_detail SSR approach
