fix: push notification registration latency on PinScreen (#423)

* fix: PinScreen dismiss response

* This fix doesn't solve the problem of long latency, however it decreases latency perception for users.

* fix: exits script after dispatch failure effect

* fix: replace BLOCKED to DENIED enum value

* fix: push notification authorization logic

* chore: extract delay from race
