feat(satellites): owner, operator and COSPAR groundwork for the orbital view

The orbital view reads a satellite's owner country, operator, COSPAR id,
TLE epoch and whether its class can be ridden. #1558 now carries only
what the class toggles read, so this brings the rest back here, where it
is first used: the classes.js helpers and the UCS pack's operator and
owner fields.
