Improve moderation behaviors: show alert/inform sources and improve UX around threads (#3677)

* Dont show account or profile alerts and informs on posts

* Sort threads to put blurred items at bottom

* Group blurred replies under a single 'show hidden replies' control

* Distinguish between muted and hidden replies in the thread view

* Fix types

* Modify the label alerts with some minor aesthetic updates and to show the source of a label

* Tune when an account-level alert is shown on a post

* Revert: show account-level alerts on posts again

* Rm unused import

* Fix to showing hidden replies when viewing a blurred item

* Go ahead and uncover replies when 'show hidden posts' is clicked
