[MIRROR] Antag HUDs will now animate if you have multiple antagonists, and will no longer clear on deconversion [MDB IGNORE] (#9397)

* Antag HUDs will now animate if you have multiple antagonists, and will no longer clear on deconversion (#62718)

About The Pull Request

This is for the admin combo HUD. Players shouldn't notice any difference (except at roundend).

Removes the ability to set custom antag HUDs for custom admin teams for complexity, though if there's a large enough demand I can try to bring it back in another PR.

Fixes #59767

TM candidate only so that I can make sure antags aren't getting leaked to people who shouldn't see them.
Changelog

cl
fix: Antag HUDs will no longer clear on deconversion if the player was another antag.
qol: Antag HUDs (as seen by admins and at the round end) will now animate between all antagonists, rather than just choosing the most latest.
