feat(mafia): Upgrades for Independent Roles

[Golbolco]

A few of the Independent roles are lacking critical features they had on EpicMafia, or otherwise could be improved.

Acceptance Criteria:

• Fool: If there are multiple Fools in the game, all Fools must be condemned to win (based on MafiaScum Jester) https://wiki.mafiascum.net/index.php?title=Jester
• Survivor: Give Survivor a Hide action. While hiding behind someone, all actions taken upon the Survivor's target will be copied (not redirected) onto the Survivor as well. While hiding behind someone, actions taken upon the Survivor themself will fail
• Sidekick: Sidekick always has a meeting with the role they have been paired with
• Supervillain: Supervillain invites all Independents to an anonymous Villain meeting (no action, simply for fun)
• Rival: All Rivals know each other, the only way to win is if all other Rivals die
• Emperor: All of Emperor's actions can be handled in the Night phase. If the Emperor's chosen winner is not one of the two people selected to duel, then there is no duel and a system message mocks the Emperor
