fix: Fix incorrect party during Investigation power

[ShrimpCryptid]

Fixes #84, "President [Investigation] shows wrong loyalty".

This was caused by a bad assumption on the original Investigation prompt card, which assumed it had access to all player roles (which is untrue as of the most recent update). I've changed it so that the prompt gets its data from a packet sent by the server instead, which I think was what it was originally supposed to do.

I've tested this change locally and can confirm that I get the correct role as both Liberal and Fascist players.
