Add Apps/Store tab, template WebUI/URL import, container RO volumes/device passthrough/run-as-user, and in-app confirm dialogs

Replaces every native confirm() with a shared P.confirm() modal (a hung
native dialog was found live to block the whole tab, including
auto-refresh, and once even double-confirmed an unrelated deletion).
Also fixes Edit Container silently resetting to Bridge/blanking the
Static IP for any container on a custom network, and a context menu
losing its anchor to a mid-read auto-refresh.
