standardizes default unfasten wrench (#65425)

I'll do more in the future but I'll limit myself to this because I'm tired, bored, and don't want to make so many PRs touching the same things that I have to deal with conflicts each time one is merged.
Just as an example, screwdriver's gotta be done as well, does the exact same thing wrenches do, I believe.
Standardizes (and touches) each time default_unfasten_wrench is used.

Fixes tool logs, since it relies on tool acts to exist, I'm trying to move as many tool acts to its proper proc. Like a spiritual successor to the tool superpack PRs.
