The energy setpoint applies via the Change Energy button, not Enter, so
it gets the full motor state machine instead of the typing-pending
color: neutral tracks the readback, a user edit stages pending (and is
the only thing that enables the button), the click turns moving, and
readback arrival within tol returns to neutral. New SpinMoveState in
motor_move_group.py adapts the pattern to a QDoubleSpinBox+button pair
(colors ride the movestate QSS via the spin's internal QLineEdit);
replaces the hand-rolled pending-until-click in the exp-config row and
covers the Beamline setup row that had no color at all. The server's
0.0 detector-unavailable energy is kept out of the readback feed so it
cannot clamp the spin to the range minimum.
