Sync mesh lean offset and disable concealment meter on remote avatars

Replicate the composed wall-lean/ground-raise/ceiling-lean mesh offset
(meshOffsetTarget.localPosition) as an owner-authoritative NetworkVariable
so remote avatars lean and raise instead of staying rigid; remote eases it
onto the visual root. Disable ConcealmentMeter on remotes (its per-frame
skinned bake, voxelization and physics overlaps only feed the local player).
SkinnedColliderBaker stays active on remotes because the paint replay
rasterizes its live BakedMesh for UV mapping.
