Say which cards give how far their orbit strays, since Pluto's does not

The date field's description read "Each moon's and dwarf planet's card says how far its orbit
strays from 1950 to 2100." Pluto is a dwarf planet on its card, but it moves on Standish's planet
elements, and the ETL measures only moons and the SBDB bodies against Horizons: its card ends
"Orbit: JPL approximate mean elements (Standish), fit for 3000 BC to AD 3000." and gives no stray
figure. In bodies.json, Ceres (7.2), Eris (0.1), Haumea (0.4), Makemake (0.3) and every moon carry
one; Pluto does not.

The description now reads "AD 1 to AD 3000, where the planets' and Pluto's elements hold. Each
moon's card, and Ceres's, Eris's, Haumea's and Makemake's, says how far its orbit strays from 1950
to 2100." The CLOCK_WINDOW comment and the scene's note comment make the same distinction.

Test: hud-dock 'opens the date field on the clock's date...' asserts the new sentence. Control:
putting the old sentence back fails that test only (1 failed, 836 passed).
