Fit the tilt wording under the Realtime prompt ceiling

With main merged, the Overpass prompt measured 55,549 against the 55,500 ceiling. The pitchDeg and direction descriptions now read 'Absolute; -89 top-down.' and 'Needed for pan/rotate/tilt steps', bringing it to 55,497. The schema pin and the measured-size note follow.
