Station Goals are now handled by SSstation instead of a global list (#81177)

## About The Pull Request

You can now get station goals in a slightly better way over using a
`locate() in` call on a global list.
The Meteor Satellite goal no longer stores a giant list of ALL OBJECTS
in view. And now correctly only counts turfs.
## Changelog
🆑
fix: Meteor Satellites no longer erroneously count every piece of paper
as a protected turf.
fix: As a result the station goal is slightly more difficult
