Round End Summary Fixes (#9096)

Added an admin verb that ends the round smoothly, displaying the end round card.
    Wizard learned spells are now properly displayed at round.
    Antags added to gamemodes they don't belong in, now properly update the gamemode's antag template, allowing their things to be displayed at round end.
    Fixed a typo in the apprentice pebble spawn-in calling it an 'artificer pebble' in deadchat.
