appview/pages: remove unneccessary wrapper div
this unecessary div causes an error where the div is duplicated when
multiple htmx requests are made.
the diff might tell a lot, but all I'm doing here is just merging
`div.relative` and `div#actions-%d` with some indent changes.
also, I removed the `w-fit` style to give pull comments full width like
issue comments have.
