I think right now there is no success if payjoin receive is successful

Closing as duplicate of #947. Payjoin status improvements consolidated there.

Reopening - this was incorrectly marked as duplicate of #947. While related, 'success screen when payjoin received' is a distinct request from 'better payjoin status text'. Apologies for the error.
