Problem
PATCH /document/:id/settings (owner-only, toggles self-join for share links) exists server-side but nothing in the client calls it. Owners can only pick link permission in ShareButton — they cannot turn self-join on/off.
Fix
Add an owner-visible toggle (e.g. inside the Share menu or document settings) wired to the settings endpoint.
