Ragdoll desync: body in rest server-side but active client-side

What happened?

When a corpse is perfectly motionless for a while, it "goes to rest", disabling the physics for performance reasons (see Ragdoll.CheckBodyInRest). It seems this is not synced in any way, so the ragdoll can go to rest client-side when it's still active server-side. This can cause problems when e.g. dragging it with a harpoon gun: the harpoon appears to attach and move the character client-side, but the ragdoll keeps teleporting to the position where it's server-side.

Reproduction steps

1. Kill a character
2. Shoot it with a harpoon before it goes to rest (you can see this when debugdraw is enabled, the ragdoll's colliders turn black when it's inactive)
3. If you get the timing right, you should see the ragdoll teleporting back to the initial position when you try to drag it.
