use template for remaining accordions

[mmagsa]

Part 2 of the accordion refactor started in 555, addressing the remaining accordions.
Also fixes a couple of small bugs (add missing </div> and &->& fix)

this is out of scope of your change but, it's funny that the remote logout accordion has a payload code block that says with indentation added for readability. but almost no indentation. seems like a ux bug to me, wdyt?

Do you mind including screenshots of this in the PR? Even after-the-change screenshots by themselves are nice. I think I've said this before, but I personally find them very helpful when trying to figure out what someone intended with a past code change when next year browsers or other dependencies may change so the page no longer renders like it used to.

@Sgtpluck good point. Not sure what the thought behind this was. Maybe more indentation would make it harder to read in the fixed-size column? I'll make a ticket to have UX take a look.

@h-m-m nothing changed visually as part of this PR. You still think there should be a screenshot?

@Sgtpluck thinking further about this - remote logout is deprecated, so I think it's ok to leave this as is.
