What can't be undone asks first

Deleting a post, taking it off the persona's wall, muting or blocking an account (from a card or a profile), leaving
a group, dropping a scheduled post and signing out acted at the first tap, a few pixels from their neighbours. They now
ask first: new ConfirmService (Ask returns whether the reader confirmed, as PublicNoticeService does) and ConfirmHost in
MainLayout, a sheet from the bottom on a phone and a dialog from md, with Cancel and the action named, in red when it
deletes or cuts off. Logout is a button that asks, then goes to /logout as before. The reversible ones (unmute,
unblock, removing a conversation from the list, a picture from the composer) don't ask; the inline confirms of lists,
filters and the login's deletion stay. The desktop tests that delete a reply, take a post off a wall or drop a
scheduled post confirm; a phone flow deletes a post after cancelling once.
