Applies the glossary across apsis-math, apsis-time, apsis-leap,
apsis-coord, apsis-geodesy and the five orbit crates that were already
implemented, plus apsis-ephemeris, apsis-maneuver and apsis-orbit. Five
hundred and seven comment blocks now carry the English paragraph and the
Chinese one.
The checker learned to skip a comment that is only a formula, since a bare
symbol has no prose to translate and repeating it in Chinese would be noise.
The SGP4 cross-check still passes, so nothing in the numerical path moved.
