Grammar checks every closet that spawns on a station. (#73331)

## About The Pull Request

All closets now are called either closets, lockers, wardrobes etc. (e.g.
the lethal injections locker was previously called "lethal injections")
Head of staff and the cook's locker are no longer proper nouns, it
didn't make much grammatical sense and it keeps consistency with other
lockers (Example: detective's cabinet)
All locker names de-capitalized except the Thunderdome ones since those
made sense.
The empty freezer is now just called a freezer since it being empty or
not depends on what players and mappers do to it.
Tram now has evidence lockers labelled from 1 through 7 instead of 7
evidence lockers labelled as 1.

Changes have been made to all station maps and in code, I've not gone
through all ruins, away missions, etc.
## Why It's Good For The Game

Cleans up a lot  of minor name issues.
## Changelog
🆑
spellcheck: All station closet and lockers have had their naming
conventions standardized.
fix: Tram now has evidence lockers labelled 1 through 7 instead of 7
evidence lockers labelled as locker 1.
