Auto-deactivate pipette after pick and remap wall-climb rotation to RMB

Reset the pipette toggle after a successful pick so each pick is a
one-shot action (HUD toggle follows via the Picked sync). Split the
wall-climb pose drag so the lean-out offset stays on LMB while body
rotation moves to RMB, letting both be held independently. Also pulls in
the terrain physics module and the user's scene setup for the terrain
test area.
