Gemeinsamer useModalFocus-Hook: Initialfokus in den Dialog, Tab/Shift-Tab
zyklisch gefangen, Fokus-Rückgabe an den Auslöser (bzw. returnFocusRef,
wenn der öffnende Menüpunkt mit dem Menü unmountet). Dialoge tragen jetzt
aria-labelledby auf ihre Überschrift und tabindex=-1 als Fokus-Fallback.

Sidebar folder view: a row now has three drop bands — the edges keep
the within-group reorder, the middle band nests the dragged page under
the row (appended to its new sibling group, with a drop-into outline
cue). Cycle/depth refusals surface as a translated banner; successful
moves are announced for screen readers.
The overflow menu gains 'Move to…': a modal parent picker over the
page tree (top level first, the page's own subtree disabled) that works
in every sort mode. Delete now decides per case: childless pages keep
the plain confirm; pages with subpages open a dialog offering promote
(default wording: move subpages up) or subtree delete.
The children lookup reads the CACHED pages list on purpose: an async
fetch before window.confirm broke the click→confirm→DELETE rhythm the
content pack (and users) rely on, and a stale childless read errs
toward promote — never toward a silent subtree delete. Sidebar caret
labels deliberately exclude the page title: accessible names are
matched by substring in the specs (#101), and a title like 'Editor…'
collided with the edit-mode toggle.
Verified live: move dialog (subtree option disabled), promote and
subtree delete flows; content/trash/export packs green.
