not receiving / processing nip46 requests

on device signing work great with Amethyst and NoStrudel.

signing via nip46 isn't working (at least on v1.0.6).

it's unclear whether Amber is not connected to relay.nsec.app (an indicator would be nice) or it is failing to process nip46 events properly. either way it doesn't respond to requests.

I love Amber and discovered this when adding nip46 support to ngit.
