Add iOS strings for Satscard integration

[PeteClubSeven]

I added the test for the one new string which uses a placeholder.

The differences from Android:

• A "Sweep Satscard" option was added to the receive actions on the bottom action bar
  • This opens the NFC system prompt for iOS
  • A success or error message is shown on the NFC system prompt when scanning a Satscard on the home page
• A placeholder retry message is all that is required for SatscardOperationDialog on iOS
• Messages that are presented by SatscardOperationDialog on Android are instead routed through the NFC system prompt for iOS
  • On Android we present a progress indicator along with the waiting text but we can't on iOS so we include the progress in the text itself as a percentage
