- Fix RowMenu JS hook dropping clicks on portaled menu items in WebKit
  (iOS/iPadOS, desktop Safari) — outside-click listener now also checks
  the portaled menu, not just its wrapper.
- Wrap hand-rolled checkboxes in <label> across settings pages so
  clicking the adjacent text toggles them, not just the box.
- Extend the Checkbox core component (disabled, wrapper_class, title,
  :description slot) and migrate checkboxes across core to it.
- Users list Location column explains itself when geolocation tracking
  is off instead of showing an unexplained "No data".
- Unify Users naming (sidebar/header) and add a page_section breadcrumb
  level to LayoutWrapper.
- Bring user detail page action parity with the Users list's row menu
  (Roles, Confirm/Unconfirm, Activate/Deactivate, Settings).
