[MDB Ignore] Adds "Red Alert Access" to EVA Doors and First Aid Supplies on all maps (#89424)

## About The Pull Request

Terminology:

- Red Alert Access allows airlocks and windoors to become all access if
the station has raised to Red Alert (or higher). This temporary all
access is reverted after the station returns to Blue Alert (or lower).
This mechanic isn't new, just not widely used.

Changes:

- Adds a mapping helper for assigning doors to "Red Alert Access"

- Gives "Red Alert Access" to EVA doors on every map

- Gives "Red Alert Access" to the first aid supply windoors in medbay
storage on all maps. Icebox already had this, which is why I thought I'd
expand it because it's a fun idea. (The doors leading INTO medbay
storage do NOT have this, meaning the CMO would likely have to set those
to emergency access.)

- Removes "Red Alert Access" from the secure storage windoor in Icebox's
medbay. Felt odd that it allowed anyone access to the syringe gun

## Why It's Good For The Game

Discussed in #89390 . 

I don't think this will be supremely impactful, but you never know. But
if anything, it may lead to people using Red Alert more appropriately
more often, which would be cool for roleplay.

The only problem is that they aren't telegraphed very well, only in
`examine`. Could probably make it more well known

## Changelog

🆑 Melbert
add: EVA doors become all access on Red Alert
add: First Aid Supplies (the compartments in Medbay Storage which hold
medkits) become all access on Red Alert (already present on Icebox).
Medbay Storage itself does NOT become all access.
