state.moveTo: unpark post-abort residue on new setpoint

When MGC's per-tick abortActiveMovements parks the FSM in
'accelerating'/'decelerating' to avoid a bounce loop, a subsequent
moveTo previously fell into the early-return path and saved the new
setpoint to delayedMove — which never fired because nothing transitioned
back to 'operational'. Now distinguish residue states from genuine
non-operational states (starting/warmingup/...) and force-transition
out of residue so the new setpoint actually executes. Also picks up
in-flight predict shareInputsFrom plumbing and pumpingStation.json
