Fix foregound service type

[hsjoberg]

In Android 14, foreground services must explain the intent of the service.

This will hopefully make phone vendors respect AOSP foreground service policies, which has been a huge problem in the past.
Samsung for example is promising to follow it: https://developer.samsung.com/mobile/app-management.html

None of the service types appear to be a reasonable choice for our Lnd service, so perhaps we should use specialUse and explain via metadata that our intent is to run Lightning network node persistently for the user, in order to receive incoming payments, et cetera.

I think abusing mediaplay might work as a fallback

I'm afraid they will punish us if we aren't honest.*

Right now I'm leaning towards using specialUse. I found out that you're supposed to declare your service in the Play Console, which gives us an opportunity to clearly explain what we want to do.

*) I use suppose we could use mediaPlay and introduce podcasting support like Breez has lol.
Or make Blixt into a music player playing music from John Berg and Dj Kazic.
