Vladislav Kopnin da464f882a Content sort: autosave without reload; keep page state across reloads ...

- drag & drop now saves in the background (700 ms debounce) without reloading:
  sections stay open, scroll position is kept; on failure it retries every 3 s,
  and navigator.sendBeacon flushes unsaved changes on page leave
- removed the explicit save button (autosave only), status indicator shows
  «Изменения не сохранены… / Сохранение… / Порядок сохранён»
- new global ui-state.js: restores open <details> and scroll position after any
  reload/redirect within the same page (applies to all pages, not just /learn)
- auto-expand a collapsed chapter/section while hovering during drag
