Add Docking Arm Checkpoints

[Carver]

This is different from the suggestion to add a residential checkpoint, thus why I made a separate thread, the scope of this is solely for the third deck docking arms.

Per the title, add shuttered checkpoints to the third deck docking arms that can be manned by Security (or accessed by any Command in emergency). Give the 'office' side of the checkpoint doors to both sides so that visitors with appropriate access (CCIA and other SCC types) aren't impaired if someone forgets to raise the shutters for them.

There's no reason that anyone who docks on the Horizon should have free access to the whole ship, and in lieu of docking codes this would suffice. Antagonists and more unsavoury responders and guests could brute-force through the doors if need be, potentially leaving a trail that someone was there for the Investigator. A final point, it would provide a logical parity with the checkpoint for the auxiliary hangar and the checkpoint for the arrivals/merchant dock - why are only half of the docks capable of having oversight?

Where would it make sense to put these? Well, there's a lounge on the starboard/west side that's never used, and on the port/east side there's a weird relaxation spot next to the upper brig that also is never used. They don't need security gear lockers, or anything besides wall-buttons and likely a security computer, so a 2x2 room should be well sufficient without being any sort of truly invasive restructuring or expansion.
