Adds three useful PDA programs to Cyborg's default PDA loadout (#86725)

## About The Pull Request

![overview](https://i.imgur.com/elfIbWM.png)
For a long time borgs have only had two PDA programs: `filemanager` and
`robotact`, but there are other simple programs with useful information
for gameplay. This PR remedies this by including three other programs to
borgs by default: `borg_monitor`, `atmosscan`, and `crew_manifest`. In
the interest of transparency, I've included possible negatives in the
form of disclaimers below.

`borg_monitor`:

This is the "SiliConnect" program in-game, and allows showing a brief
overview to cyborg players who else is connected as a cyborg and what
their model is, which allows for informed decisions on which module to
choose for themselves, among other minor useful data.

**_Disclaimer: I'm pretty sure the "Send message" button on this program
is unusable for borgs due to how it's coded
[here](https://github.com/tgstation/tgstation/blob/ab222330ef3b05f512d9b0a87c3292377ce91271/code/modules/modular_computers/file_system/programs/borg_monitor.dm#L116),
but I'm unable to test it with another player. Looks like it requires an
ID, which borgs don't have, so I'm assuming this is a non-issue._**

`atmosscan`:

The AtmoZsphere program, which shows local oxygen/nitrogen data to help
make informed decisions on protecting humans.

`crew_manifest`: 
![crew](https://i.imgur.com/7OWeM4i.png) 
The Plexagon Crew List - A simple window that shows an updated list of
current crew members and their jobs.

**_Disclaimer: The "print" button on this program allows borgs to spam
printed crew manifests on the ground if they choose to do so, which may
have the potential to be overused, however they've also had the ability
to spam-print photos using the Robotact program and I don't know of any
issues this has caused (correct me if I'm mistaken)._**
## Why It's Good For The Game / Potential additional changes

Currently cyborg gameplay can become a walking simulator if they need
simple information that a crew manifest computer would have, or an air
alarm (which might've just been blown up, disabled, or out of power), or
if they just got borgified at a Roboticist and would like to know which
other cyborgs are currently in play but don't want to pick a model
already being used. All humans have this data and more on their handheld
PDAs. Cyborgs should at least have these three as a bare minimum.

There are other useful programs: `records/medical`, `records/security`,
`custodial_locator`, and `supermatter_monitor` (NT CIMS), which could go
into Mediborgs, Peacekeepers, Janiborgs, and Engiborgs respectively.
I've tested these and am unable to change these records as a borg, only
view them, so this is purely informational data that could be useful for
various RP reasons. It could be fun for a cyborg buddy to patrol with a
Sec officer (or Paramedic) and give them up-to-date info on a crew
member's status just by having the human ask about them. Or, Engiborgs
are given the ability to keep an eye on the Supermatter using NT CIMS
and can inform engineers out in the field of its status.

Just having this general information available only to humans feels a
bit silly when cyborgs are meant to be connected to the station in a way
that allows them to interact with doors from a distance but not
something simpler like viewing a crew manifest. This still keeps the
power in human's hands since this data cannot be manipulated by borgs,
only humans (ID required).
