P11: hide fogged tokens from players + show combat conditions

- toPlayerProjection now drops tokens whose footprint is unrevealed when fog is on,
  so a token's name/position stays hidden in the dark (tested).
- Player initiative view shows each combatant's visible conditions (playerCombatant
  + wire schema + PlayerBoards chips) — monster conditions are now visible to players.
