Medical Kiosk right clickery, balloon alerts and screentips (#77854)

## About The Pull Request
Moves pulling the scanner wand from alt click into right clicking with
an empty hand.
Turns a few `to_chat` into balloon alerts.
Screentips.
## Why It's Good For The Game
Firstly, right click is just better UX than Alt clicking IMO.
I often talk with people that have no idea you can pull the scanner wand
from the kiosk to check on other patients.
That is such a neat feature and I just want it used more, so I hope this
nudges people to learn about it easier.

I did plan on also adding a new sprite for when the kiosk has a wand,
but after a few attempts I gave up for now, maybe someday I have more
patience I come back to it because it would help way more than these
changes...
## Changelog
🆑 Guillaume Prata
qol: Medical Kiosk now have their wand removed with a right click, got
new screentips and have a few of its chat messages turned into balloon
alerts.
