Add player-collision toggle and make conversion statues follow it

Add a per-machine "Players Collide" switch on GameModeManager: a
self-healing reconciler routes the local capsule through other avatars'
body colliders via Physics.IgnoreCollision when disabled, re-asserting
every frame while off to survive the late-created runtime MeshCollider,
conversion respawns and teleport resets. Expose Active/ActiveVersion/
BodyCollider on NetworkPlayerSetup for the reconciler.

Give MatchStatue the same Active registry + BodyCollider pattern so the
frozen conversion statues obey the same toggle (they carry their own
paint MeshCollider but are deliberately not NetworkPlayerSetup avatars).
Also drive the statue's steady X-ray reveal in Resolution, matching an
un-found hider.
