Description

The context menu ("three dots") of the current breadcrumb item was only available in the desktop breadcrumb. On mobile, users had no way to access the actions for the current folder from the breadcrumb.

This PR renders OcBreadcrumbContextMenu next to the current folder in the mobile breadcrumb as well (.oc-breadcrumb-mobile-current), using the same showContextActions condition and contextMenuPadding as on desktop. Each OcBreadcrumbContextMenu instance generates unique trigger/drop IDs, so the desktop and mobile instances don't conflict. The inactive variant is hidden via the existing Tailwind breakpoint classes.

The context menu drop now also uses the current folder name as its title, which is shown in the bottom drawer on mobile.
