Add moderation icons to user cards

[goto-bus-stop]

about time we get these 😂

This made me think that our mute/ban situation is a bit strange. Muting only affects chat but still allows joining the queue. Bans do not allow users to log in but they can also be temporary. It's inherited from plug.dj but I think we can make it more like Twitch, with bans just being permanent, and timeouts allowing the user to join the room but not to interact (no voting, no chatting, no joining the queue). Banned users should probably also be able to use some other parts of the site still like viewing playlists. Maybe not any modifications though, as a reason for the ban may be abuse of features that don't actually affect other users of the site directly, but affect the site itself.
