Once we have a signal from the recipient, we need a way to propagate this information throughout the route. Including a signal in the onion provides an uncorruptable way for the sender to propagate this signal. If the sender is dishonest, this will eventually be detected by the final recipient. In the commits that follow we'll add reputation and resource management that will allow nodes to use this signal to protect against jamming attacks.
h/t elnosh for pointing this out!
Follow naming convention by prefixing invoice fields with "invoice_".

Blinded routes do not allow the sender to send custom payloads to nodes inside a blinded route (https://github.com/lightning/bolts/blob/master/04-onion-routing.md?plain=1#L315), instead all the payload data is chosen by the recipient and is put inside
encrypted_recipient_data. For this reason, when using blinded routes, theupgrade_accountabilitymust be set by the recipient insideencrypted_recipient_dataand not in the payload by the sender.
