fix: revert to showing only active players in room games

Reverted getRoomActivePlayers() to use getActivePlayers() instead of
getAllPlayers(). Room games should show only players marked isActive=true
from each room member, not all players regardless of status.

Behavior:
- Room mode: Active players from all room members
- Solo mode: Active players from current user
