Add slider captcha for web login, VitePress documentation on GitHub Pages,
and fixes for gallery delete refresh, pagination jump, and copy-format persistence.
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.
Add per-user activity logs with storage backend tracking, gallery
storage filter, and IP/token upload rate limiting. Fix storage delete
modal flash, pin local backend in filter order, and link settings
version to GitHub releases.
