audit tag renames

[cellio]

Adds tag renames to the audit log -- merges are already there, and renames, like merges, don't leave visible history other than the log. Fixes #1638.

I should probably figure out how to add a test, but there's no merge test for me to piggyback on so I'm a bit lost. I didn't find any existing tests that check the audit log.

I do not understand the system-test failure (is it spurious?).

Yeah, system tests are just flaky, it's annoying, but for now until I or someone else sits down and fixes them, the only remedy is to rerun the workflow whenever it fails on CircleCI (https://app.circleci.com/pipelines/github/codidact - you should have access to it via the org - just "rerun from failed" if no one's around to do so - might take a couple of tries, though):

Adding tests for audit logs should be relatively straightforward: just test the controller method in question and then ask the model to get you the most recent audit log of the relevant type - even checking that it's there at all should be enough

I've added the test (not for the audit log, but for the controller method - it's more important to have the base functionality covered - if you want to get some practice, feel free to add one specifically for the log [best to just expand the test I've made] - do ping me if you need help with that) and several fixes (will comment on them separately).

I got Post.transaction from merge a few lines down. Do we need to change it there too? Or is that one correct because tag merges modify posts?

Those fixes were educational. Thank you!
