Require a user tap to launch the Nostr signer (fixes Amber malformed)

Browse Source 
Amber v6.2.0 routes nostrsigner: intents by EXTRA_APPLICATION_ID: present
(web flow, reads the event from the URI) vs absent (app-to-app flow,
reads type/event from intent extras → rejects our URI as malformed).
Browsers only attach that extra when the external-app launch comes from a
user gesture, so the auto-redirect on page load always failed. The
launcher now waits for the user to tap "Mit Amber signieren".
