Verify storage files before serving from the index, disable CDN caching
on image 404/403 and host-isolation blocks, and retry gallery thumbnails
after transient load failures.
Add storage_use_date_path for flat vs date-key storage layout and emit
basename-only public URLs when hide-folder is enabled. Block image paths
on the site host when domain separation is active so only the image host
serves files. Update settings UI, i18n, tests, and deployment docs.
