Daniel Agar 177613eb68 ekf2: GNSS velocity control should own vertical velocity reset if height faiing
- GNSS height control using the velocity sample directly is ignoring
   potential position offsets

Daniel Agar ac77049c47 ekf2: directly use IMU sample to find corresponding aid source sample
- I think this helps make it clear we're using a sensor sample
   corresponding with a particular IMU sample

Marco Hauswirth 419652b9fe EKF2: Spoofing GPS check (#23366)
* estimator gps check fail flag for spoofing

* warn whenever spoofing state changes to true, use default hysteresis to completely stop fusion

* dont introduce more GPS namings, GNSS instead

* flash: exclude mantis for cuav_x7pro

Daniel Agar ea8f14b883 ekf2: optical flow logic, timeout if bad_tilt, etc
- previously we could get stuck with optical flow still technically
   active (_control_status.flags.opt_flow=true), but nothing being
updated due to excessive tilt, etc

Daniel Agar 8bf15b01c4 ekf2: optical flow don't compute innovation variance twice
- collapse updateOptFlow() and startFlowFusion() to avoid recomputing H
 - this is a relatively expensive call we can easily avoid with the
   right structure

Marco Hauswirth e04c53241a EKF2: reset position by fusion (#23279)
* reset position by fusion

* handle local_pos_valid for fixed wing in gnss denied

* [WIP] ekf2: setEkfGlobalOrigin respect current height reference and vertical position aiding

* global origin, also reset vertical pos without gps as ref

* fix wo gnss, that bitcraze ci passes

* revert some changes as requested

* remove duplicate reset messages

* undo unrelated whitespace changes, I'll fix it everywhere in a followup

* [SQUASH] ekf2: add vehicle_command_ack

* resetGlobalPosToExternalObservation consolidate logic

* remove gnss check from local_pos validation check

* reset when  0<accuracy<1, otherwise fuse

* replace gps param with flag

* ekf2: dead reckon time exceeded, respect ZUPT preflight if air data or optical flow expected

* subtract timeout from last inertial dead-reck, change fake pos conditions, save flash

Daniel Agar 0742d356f5 ekf2: more conservative clipping checks for bad_acc_clipping fault status (#23337)
- track accel clipping count per axis
 - only set bad_acc_clipping fault_status if at least one axis is
   clipping continuously or if all have been clipping at warning level
 - Note: this doesn't impact the clipping projections that boost the
   accel process noise, pause bias estimation, and skip gravity fusion
   on a per sample basis

 - logger optionally log all estimator topics at minimal rate

bresch a50ef2eb5e ekf2-terrain: make terrain validity based on uncertainty
When using optical flow for terrain aiding, we cannot assume that the
terrain estimate is valid if flow is fused as is can only be observed
during motion. When no direct observation is available, the terrain is
assumed to be valid if its 1sigma uncertainty is < 10% of the hagl.
