fix: Request CAMERA_SETTINGS on zoom and focus

[jnomikos]

Description

The changes from PR #13612 do not actually end up requesting CAMERA_SETTINGS whenever zoom level or focus changes. Thus, QGC may request CAMERA_SETTINGS (and thus CAMERA_FOV_STATUS) once, but it won't necessarily do so after that. This could result in the FOV stored on QGC not actually reflecting the FOV of the camera after zooming.
