adopt pre-modelrevert clearpilot tree (d639e28) as the new head

Discard the modelrevert tree adoption (8b4b7e0) and the in-process park
short-circuits / cached-output / dashcam-idle work that came with it
(0dc8002, 37e095e). Restore the clearpilot tree as it stood at d639e28 —
the parked-controlsd manager-process split, the GPS-disable in locationd,
the controlsd UI hooks, the boardd ignition-edge safety_setter_thread
fix. After a full /data/params/d wipe and re-calibration drive, the
modelrevert-tree variant overcorrected on turns; reverting to the
parked-controlsd architecture (which Brian had previously vetted and
documented in 887b9c9 + 27cad05) and starting fresh.

Single new commit, no merge — file state matches d639e28 byte-for-byte.
