Change how changes to media attachments are stored for edits (#17696)

* Change how changes to media attachments are stored for edits

Fix not being able to re-order media attachments

* Fix not broadcasting updates when polls/media is changed through ActivityPub

* Various fixes and improvements

* Update app/models/report.rb

Co-authored-by: Claire <claire.github-309c@sitedethib.com>

* Add tracking of media attachment description changes

* Change poll in status edit to have a structure closer to the real one
