Support sweeping inscriptions from satscards

[casey]

It would be cool if you could transfer an inscription to a sats card, and then sweep it from the ord wallet. It would be also cool if you could easily see which inscriptions are in a sats card.

The pieces of this are:

1. Make satscard links work with ord, and show you which inscriptions are in the satscard. When you tap a satscard, it opens a link to a website which shows you the bitcoin value of the satscard. We should make it so if you replace the domain with ordinals.com, it shows you the inscriptions in the sats card. (Eventually we can beg NVK to make us custom satscards that point directly to ordinals.com)

2. Make ord communicate using an external NFC reader with the satscard so it can unlock it, get the private key, and sweep the inscription from it. You would need an external NFC reader for most laptops, but it's such a cool use-case that I think it's worth exploring.
