* fix(fw_mode_manager/navigator): use the correct switch distance
Before https://github.com/PX4/PX4-Autopilot/pull/24056, the fixed-wing
position controller used to publish the acceptance radius (calculated
depending on params and state by DirectionalGuidance::switchDistance) in
the position controller status.
The refactor migrated that to individual lateral/longitudinal topics,
but left the receiving code in the navigator unchanged. As a
consequence, fixed-wing vehicles now rely on NAV_ACC_RAD for the
acceptance radius, rather than the adaptively calculated switchDistance.
As NAV_ACC_RAD is only 10m by default this leads to overshoot,
especially on tight corners.
Fix by reintroducing the publication (now from FixedWingModeManager
through fixed_wing_lateral_guidance_status) and using it in navigator.
* fix(navigator_main): only listen to position controller status if rover
rover_ackermann is the only remaining publisher after #24056
* style(msg): improve field description
- @INVALID NaN
- Describe relation with NAV_ACC_RAD
* style(fw_mode_manager): remove stale include
* docs(navigator): clarify acceptance logic in param description
