John Willard aa820c08fe Oldstation now has their own RND (#78132)
## About The Pull Request

This PR does many things and I expect to be asked to atomize some stuff.

### Oldstation Additions

Oldstation now has their own research server, generating their own
points. To help alleviate major concerns, they have a few stuff to help
with this:
- They now have a pre-built operating computer
- They now have an Autopsy scanner
- They now have access to Experimental Dissection

Experimental Dissection is the old dissection, giving research points in
the form of paper notes on completion. They must be turned in to the RND
server (only works on the Oldstation one, so you can't abuse this) for
points. This was an idea I've had for some time, as Oldstation is used
somewhat as a representation of how ss13 used to be (through its use of
directional windows (before they got removed, but I'd like to bring them
back), old IDs, RTGs, and old engines before they got removed from the
game fully)

Considering there are 11 alien mobs in Oldstation, there is 27.5k
research points to get from alien corpses, enough to bring them up to
speed with whatever they wish to do. This is their 'alternative' for
experiments (which they can still do if they want, but it is very hard
to do, outside of dissection which is needed for the node).

This surgery isn't repeatable, isn't upgradable, and isn't removed by
being healed. It is not mutually exclusive with autopsy (so you can't
ruin yourself doing the wrong surgery).

### Other stuff

- Ninjas now drain RND points from the server they drain from, rather
than always hitting science
- Syncing machines to research roundstart is now a macro, and now
immediately syncs to a server on your Z-level. Machines will
automatically connect to the Science servers if none else are available.

### non-player facing

- Science, Admin, and Oldstation techwebs are now no longer vars on
research, but stored in research's list of techwebs.
- ``get_available_servers`` and ``find_valid_servers`` are now procs on
the research subsystem, rather than the experisci component.
- Oldstation code has been split into separate files.

## Why It's Good For The Game

Oldstation is one of my favorite ruins, but it is also one of the
largest complaints for RND (along with Golems) because they use the
station's Science nodes & points (I recently tried de-hardcoding Science
stuff to help prepare for this, but I didn't get everything in advance).

The complaint stems from these ghost roles, who are meant to be a fun
activity to do while waiting for the next round, using the station's
research points for their own stuff, completely untrackable unless
someone goes out of their way to grief a ghost spawn just for using
points to get things they need. These roles make their own servers to
drain the station, and I find that unfun and quite boring for everyone-
it's also not very flavorful, why would Charliestation know of the
station's RND to take advantage of it?

This hopes to fix those issues, make Charliestation more worthwhile, and
more flavorful.

## Changelog

🆑
fix: Getting a node researched now properly makes it no longer hidden.
fix: Ninjas draining RD servers now drains it from the connected
techweb, rather than sniping Science.
balance: Machines will first try to connect to a techweb with servers on
their z-level, with the Science techweb remaining as fallback.
add: Oldstation RND, comes with their own Techweb and special surgery to
gain research points through dissecting Xenomorphs.
