bark: Fix 'ln status' can't find payment hash for outgoing payments

This PR fixes a bug where bark ln status <payment_hash|invoice> reports “No invoice found” for outgoing Lightning payments, even when the payment was successful and visible in bark movements.

The issue occurred because the command only checked Lightning receives (incoming invoices) and ignored Lightning sends (outgoing payments).

This change extends the lookup logic to also check Lightning sends, allowing ln status to correctly resolve and return the corresponding payment_hash or invoice for outgoing payments.
