Torso elevation (pitch aim) wired: the pod stick's Y axis lives

Browse Source 
The mechs could always tilt their aim up/down -- Torso models the full
vertical axis (currentElevation, rate, VerticalLimitTop/Bottom,
recenter) and EVERY 1995 control mode routes stickPosition.y into
Torso::SetAnalogElevationAxis -- but the desktop bridge hard-zeroed
stick Y, so the axis was dead on a keyboard rig.  The one pod control
the remap left unwired.

- btinput: JoystickY axis -> elevTarget/elevActive/elevAbsolute
- mech4 shim: sElev integrator (same walk/spring model as the twist;
  X recenters pitch too via gBTElevRecenter)
- mechmppr bridge: feeds stickPosition.y every bridged frame (the old
  unconditional zero removed); both mode branches covered
- CONTROLS.MAP (+ numpad profile + compiled default): R/F = aim
  up/down, pad LeftStickY = elevation (was unused)
- torso.hpp: CurrentElevation()/ElevationVelocity() accessors (diag)
- [mppr] trace gains stickY (note: the trace reads AFTER the next
  frame's device push re-zeroes the stick -- input flows regardless)

Verified live: R held -> torso elevation climbs at the authored rate
and clamps at 0.349066 rad = exactly 20.0 deg (the Blackhawk's
VerticalLimitTop); release holds the aim.  The eyepoint correctly
stays level -- pitch aims the GUNS and reads on the HUD's vertical
elevation tape, as in the pod.
