improved detail in game log messages in chat

[danwang]

suggestion: if the backend can return structured data message like

{
  type: 'play',
  player: PlayerID,
  cards: Array[Card],
}

we could render in the chat more detailed information, like

• rendering cards as displayed number + suit instead of the card text
• making names clickable, or rendering them in a different color depending on team

this seems very reasonable / not very hard to do!

We'd want to update the messages returned from functions on GameState to be a new GameMessage enum which derives Serialize and Deserialize, and render the relevant strings in the frontend.
