MOXIE DIGITAL - PRODUCT IMAGE RUNTIME FIX

Purpose
- Fixes Admin-uploaded product images that were saved but showed as broken/blank on the website.
- Makes /api/media/site-images/<filename> route to the protected ULTROX media gateway BEFORE the generic /api router.
- Keeps existing Admin/API authentication intact.

Install on cPanel/shared hosting
1. Back up public_html/.htaccess, router.php and secure-asset.php.
2. Extract this ZIP directly into the website document root (public_html for moxiedigital.in), replacing those files.
3. DO NOT delete or replace your existing api/ folder. This patch intentionally does not include api/.
4. Clear browser cache / Ctrl+F5 and retry Product Icon or Product Card Image upload.

Important
- Existing uploaded files under uploads/site-images are preserved.
- The generic API remains responsible for authenticated POST /api/admin/images uploads.
- The patch fixes the broken runtime display route used after a successful upload.
