Function test_lnurl_recovery 

pub(crate) async fn test_lnurl_recovery(dev_fed: &DevJitFed) -> Result<()>

Tests LNURL receives after recovery from seed.

LNv2 uses NoModuleBackup, so recovery restores funds via the mint module but not the operation log or LNv2 state. Verifies:

1. Balance is fully recovered.
2. Payments to a pre-recovery LNURL are still claimed by the restored client.
