- remove commander test ratio "tuning knobs" (COM_ARM_EKF_{HGT,POS,VEL,YAW})
- these are effectively redundant with the actual tuning (noise & gate)
in the estimator, plus most users have no idea why they'd be
adjusting these other than to silence an annoying preflight complaint
- remove ekf2 "PreFlightChecker" with hard coded innovation limits
- ekf2 preflight innovation flags are now simply if any active source
exceeds half the limit preflight
