Update chat message visibility for moderation (#524)

* update message viz in db

* create admin endpoint to update message visibility

* convert UpdateMessageVisibility api to take in an array of IDs to change visibility on instead

* Support requesting filtered or unfiltered chat messages

* Handle UPDATE chat events on front and backend for toggling messages

* Return entire message with UPDATE events

* Remove the UPDATE message type

* Revert "Remove the UPDATE message type"

This reverts commit 3a83df3d492f7ecf2bab65e845aa2b0365d3a7f6.

* update -> visibility update

* completely remove messages when they turn hidden on VISIBILITY-UPDATEs, and insert them if they turn visible

* Explicitly set visibility

* Fix multi-id sql updates

* increate scroll buffer a bit so chat scrolls when new large messages come in

* Add automated test around chat moderation

* Add new chat admin APIs to api spec

* Commit updated API documentation
