Support authme action from URL query

Read the 'action' value from URL query params and handle a new 'authme' action. When 'authme' is present, prompt the user to approve redirecting to the provided redirectURL; if approved, append the current auth token as a 'token' query parameter and navigate to that URL. The prompt is shown in two places (after auth data is updated and before loading the desktop) to cover different entry flows. Also removed a stray blank line.
