Fix: Use storage.url() for tenant-aware image URLs in frontend

Updated ImageService to use default_storage.url() instead of manually
constructing URLs. This ensures images displayed on the frontend correctly
include the tenant_id in the path, enabling proper file access within
multi-tenant environment.

Changes:
- ImageService.get_url() now delegates to default_storage.url()
- All image URLs now include /media/tenants/{tenant_id}/ path
- Ensures consistent behavior with TenantAwareFileSystemStorage
- Frontend photos now display correctly with tenant isolation

Result:
- Thumbnail URLs: /media/tenants/papa/products/4/28/thumb.webp
- Medium URLs: /media/tenants/papa/products/4/28/medium.webp
- Large URLs: /media/tenants/papa/products/4/28/large.webp
- Original URLs: /media/tenants/papa/products/4/28/original.jpg
