backend/transaction: auto select highest fee for payment requests #2836

Closed Beerosagos closed 3 months ago

There was a bug in the payment request implementation that didn't correctly support mempool.space fees and resulted in a fee error during the tx proposal on production environment.

This commit moves the fee target selection for payment requests in the BE and fixes the bug.

Moved all the FeeTargets code to coins/btc/feetarget.go and added unit tests. Thanks :pray:
