Add inline title/description editing and list delete to the list view

ListView: the title and description are now inline-editable fields saved on
blur via PATCH /api/lists/:id; an empty description shows an "Add a
description" placeholder. A "Manage" menu in the top right (click-outside and
Esc to close) holds a "Delete list" action that opens a confirmation modal;
confirming calls DELETE and routes back to the all-lists view. No backend
change — the existing PATCH/DELETE endpoints cover it.
