I keep getting handed the same bad WU. So far it's been logged as a failure 57 times and it's still cranking on the 58th attempt (it's always the same WU). It fails at 83% every time, having wasted a bunch of CPU cycles and electricity...

How can I get rid of this (apparently) bad WU and move on?:

The WU (P6502,R17,C153,G20) has been reported as a bad WU.

Moderator reports will stop a WU from being issued, but they' are not processed instantly and sit in a queue for maybe an hour or so.

The official method to dump a WU is to run with the -delete 04 flag (since your log says "Working on Unit 04"). If you're certain that you don't have anything in your queue waiting to upload, you can delete the /work folder and queue.dat (with the client stopped). The server may reissue the same WU so you may have to do that more than once.
