Was not super visible, especially without HR as the dialog immediately
closes (limitation of the web client), or when an administrator user
massively disables totp.
Show a toast notification indicating the success of the action.
Also fix the logging of `totp_disable` so it correctly handles being
called on more than one record, and change the logging data to
<browse_record> (<logins>) across the board.
Also add a way to provide an action to execute after a notification:
by default nothing happens, which leads to dialogs not closing and
forms not reloading, and there is no good way to show a notification
and/then do some other thing, which is inconvenient.
