Tweaks (#22965)

* use ffmpeg to probe rtsp urls instead of cv2

cv2 is faster (no subprocess launch) and will continue to be used for recording segments

* tweak faq

* change unsaved color to orange

avoids confusion with validation errors (red)

* don't use any variant of orange as a profile color

avoids confusion with unsaved changes

* more unsaved color tweaks
