fix(satellites): stop matching a mission to a namesake from another year

The mission orbit lookup reads each loaded satellite's launch year from its
international designator, but satellite.js never parses that field, so the
year check never ran and a new payload could take an older namesake's orbit
and position. The loaded catalog now keeps the designator from the TLE line.
