hv_enable: EV_SW bit 4 is the HV_ENABLE readback; pins for the rename

SAFETY.md and the safing figure name GPIO4_06 for what it is - the
readback of the chain's HV_ENABLE output through U24 (the factory net
label E-STOP is kept as a note); BRINGUP records the rename, the
device-tree polarity flip that makes bit 4 read as HV_ENABLE itself,
the removal of the estop_halts_motion opt-in, and the bench check for
the flash that ships it. Recipe pins move to forgectrl 801f1f3,
grblHAL-glowforge b629c18 and python3-gfhardware c3d1790 (PV 0.1.5).
