8116 Show correct tap/insert/swipe reader message

joshheald · joshheald · commit 95f5e23719c2 · 2022-11-16T16:10:24.000Z
Previously, we did not take account of the ReaderInputOptions returned to us by the Stripe Terminal API, instead we always displayed “Tap, insert, or swipe to pay”, even when those options were not supported, or the SDK was requesting a different method.

This change passes the ReaderInputOptions to the View Model concerned with showing this message to the merchant, and converts the various supported options into specific localized strings, along with a (currently unused) default of “Present card to pay”.

To see this in action, compare the messages shown when using a US card reader (M2 or chipper, which both support swipe reads) to a CA reader (which only supports tap or insert reads.)
