It's my understanding that this PR fixes that the refundable swap is no longer shown in list_refundables. I have two questions, after executing a refund:
- Is the payment shown with the refund_tx_id in
list_payments? - Is it possible to broadcast another tx to effectively bump the fee?
My concern is the swap is no longer refundable if broadcasting the refund with too low a fee

Yes.

Only for cooperative refunds. The non-coop refunds don't have RBF enabled.
However there is no timeout after which cooperative refunds are impossible. The only way I could test non-cooperative refunds was by commenting out the coop refund call. Boltz participated in the coop refund even weeks after a swap failed.

From what I can tell, this can only happen if
- Boltz is not reachable for the coop refund and
- the user chooses a feerate that is too low
IMO this is unlikely because of the 1st point.

I tried on main branch to do this, but I get a "No UTXO found" error. Probably because the electrum script_list_unspent excludes them "Any output that is spent in the mempool does not appear"
Boltz participated in the coop refund even weeks after a swap failed
I think Boltz will always try to cooperate with a refund (always if the lockup failed or if the swap expired after they refund themselves). So it's more doomsday handling
Fixes #432
