Add "reinstall phoenix" as a fix suggestion to fcm error note

[renepickhardt]

I had an old phoenix wallet and this FCM warning kept popping up.

phoenix/phoenix-android/src/main/res/values/important_strings.xml

Line 108 in 34e00ff

<string name="home_background_restriction_fcm_details">If you\'re on GrapheneOS or CalyxOS, install Google Play Services to get FCM notifications. Check the FAQ for guidance.</string>

Even updating and changing phones settings wouldn't change anything. I realized that the fcm token may need to be refreshed. Reinstalling the phoenix worked. Maybe the message should be extended to suggest reinstalling if on regular android.

I'd open the PR with a patch but I am unsure about all the internationalization and translation.

I had the same issue; I used the Android built-in tooling to migrate from a Pixel 6 to a 10 Pro, both running their stock distribution of Android (not Graphene), and had this issue as well.

Reinstalling and seed restore + payments database restore did indeed resolve the warning; I tested an incoming payment to my BOLT12 address and that also worked.
