Also here's the output of btrfs-find-root:

Not sure where to go from here.

I can't say for certain, but that suggests that the move-via-dd didn't
succeed / wasn't correct, and/or the partitioning changes didn't
match, and/or the dd happened from a mounted filesystem (which would
also explain the transid errors, if there wasn't an unclean umount
involved).

btrfs-restore might be able to pick out files, but you may be in
restore-from-backup territory.
