Blueshift 4: Shift Harder (#3904)

## About The Pull Request

Resurrects everyone's favorite map, with some spit-shining.
- [x] Update all paths so it compiles (obviously)
- [x] Fix some disconnected cables
- [x] Add extra firelocks to the main foyer area
- [x] Add Captain's cast to the cap's office
- [x] Add detective caseboards to the detective office
- [x] Do a pass over security camera coverage, several departments were
missing massive amounts of cameras in areas
- [x] Do a pass over external airlocks, sided all access on these is
reportedly weird on certain docks
- [x] Do a pass over department wall signs (the direction ones) and make
sure they're not wrong
- [ ] Potentially clean up some of the worst offenders of
"impossible-to-navigate maints"
- [x] Ensure we're not missing any standard every-map additions that
have been created since it was decommissioned
- [x] ???
- [x] Secret things I don't know about yet because people are going to
give me feedback
