VCAuthN proof UI references to BC Wallet to adjust

For "BC wallet cleanup" epic when that's created. Wait on any action on this until deciding when to go forward (likely not needed before single-app release?)

VCAuth has on screen references to the old BC Wallet naming. Will need to adjust that to "BC Services Card" or whatever appropriate. This may need some UX discussion if the name gets long in terms of how it looks on the buttons for mobile?

Start by locating the VCAuthN proof UI screens shown in the attached image and identify every on-screen reference to the old BC Wallet name. Wait for the BC Wallet cleanup decision and UX discussion about the longer BC Services Card label; done means the agreed wording is applied consistently without harming the mobile button layout.
