Saibernard 2de7ab05fa fix(gz_bridge): support GPS failure injection (#28398 )

* fix(gz_bridge): support GPS failure injection

Modern Gazebo publishes sensor_gps directly from GZBridge, bypassing the shared failure-injection processing. Route each NavSat sample through process_gnss using the actual uORB publication instance so off, stuck, wrong, and recovery work for the addressed receiver.

Add functional regression coverage for the real GZBridge NavSat callback and sensor_gps publication path, plus recovery coverage for the shared GNSS processor.

Fixes #22296

* docs: gps failure injection is available on Gazebo

The gz_bridge now applies the shared GNSS failure state to the
simulator's NavSat data, so the table entry and the SIM_GZ_EN_GPS
workaround note are out of date.
