fix(sidebar): auto-refresh after creating a doc from the reader toolbar

The reader's inline "New Document" button (createChildDocument())
only navigated to the new document — no handle on the sidebar row it
landed under, so the tree stayed stale until the periodic
remote-changes poll surfaced the reload banner.

Right-click "New Document" on a collection already refreshed correctly
(bumps its own documentsRefreshToken) and is untouched.

Threads a documentsChangedToken from ContentView_macOS down through
CollectionsTreeView -> CollectionTreeRow -> CollectionDocumentsOutline
as externalRefreshToken; every expanded row reloads itself when it
bumps, since the reader doesn't know which row (if any) corresponds to
where the new document landed.
