Two changes which fix#4807:
- Once permissions are granted we start scanning immediately, no need to ask for permissions or have the user click the button again
- We don't abort the scan, which gets rid of the cases in which the OS took over after the scan, because the user left the card on the device
Also adds feedback for the NFC states scanning and submitting.
Fixes comparisons of `long` and `LightMoney`, which did not work, because the `amount` provided was in sats and Lightmoney compares to millisats.
Closes#4663.
