[Game] Prevent spectator duplication when replaying joined events (#7248)

Browse source 
* [Game] Prevent spectator duplication when replaying joined events

The spectator branch of eventJoin emitted spectatorJoined unconditionally
even when the spectator was already present (e.g. replayed during a rewind).
Guard it like the player branch and eventGameStateChanged, and make
PlayerListWidget::addPlayer idempotent as defense in depth.

* In resetChatAndPhase() (the rewound() handler), also clear all spectators from both PlayerManager and PlayerListWidget before the replay rebuilds from event 0. The forward replay then re-adds exactly the spectators whose join events fall within the new time range via eventGameStateChanged/eventJoin.
