Luckily, we were able to sort this problem out by rebooting the hosting
machine and restoring the guest machine from a backup. Did we stumble
upon a bug? "blockjob abort" should not leave behind orphaned locks when
it completed, should it?

Houston, we've got a problem. We have roughly 16 hours to fix this. Any
help is appreciated!

improve our daily backup cronjob to retry blockcommit after a blockjob
abort, but it feels so hacky that I would do that only as the last resort.

Note that this does not help with the original problem but points out a
critical design flaw.
To me your it infrastructure design has no working disaster recovery plan.
You should always be able to access critical functionality and from there
be able to restore complete functionality step by step.
fit your needs or even improve it and open pull requests!
