Area definitions cleanup (Horizon/Runtime) (#20914)

**Goals:**
1. Delete area definitions no longer used in any map or file.
2. Update area definitions such that everything used in mapping the
Horizon exists in 'maps\sccv_horizon\areas' with the parent
'area\horizon\'.
3. Reorganize/rename/restructure those Horizon area definitions to make
future mapping easier and code that hooks into area properties easier.
4. Present area names and blurbs in the status panel.

This PR only handles Horizon and Runtime areas, for digestibility/ease
of reviewing. Offsite areas for another PR.

Naming convention reference:
The /area/ 'name' variable no longer contains either 'Horizon' or the
Deck# of the area or its approx location on the ship. All Horizon areas
now have several new variables as metadata-- area names now need only be
strictly descriptive, and the appropriate constants used in the area
definition, and a new function generates the display name with
consistent formatting for us.

Detailed documentation to follow after any adjustments are made to
mappers' preferences.

This also adds area blurbs to most areas- if not bespoke, then general
department-wide blurbs to parents. I know feature creep always sucks,
but while some areas having pre-existing blurbs, the overwhelming
majority of areas don't, and while testing it was very distracting to
see them randomly appearing and disappearing. Most blurbs are pretty
basic but I feel are entirely presentable- more clever individual ones
can follow in a separate PR.

+/**
+ *	This file is the only location in which runtime map areas should be defined.
+ *	Each department (or other appropriate grouping) will have its own section that you can jump to with ctrl-f.
+ *	For convenience, these groupings are:
+ *	CREW_AREAS
+ *	COMMAND_AREAS
+ *	ENGINEERING_AREAS
+ *	MAINTENANCE_AREAS
+ *	MEDICAL_AREAS
+ *	OPERATIONS_AREAS
+ *	SCIENCE_AREAS
+ *	SECURITY_AREAS
+ *	SERVICE_AREAS
+ *	TCOMMS_AREAS
+ *
+ *	GUIDELINES:
+ *	- The Horizon should not have any areas mapped to it which are defined outside this file.
+ *	- Any PR that removes all areas of a given definition should also remove that definition from this file.
+ *	- No area should exist across multiple decks. Ex., an elevator vestibule on all three decks should have three
+ *	child definitions, one for each deck. This is both for organization and for managing area objects like APCs etc.
+ *	- Update the groupings list if anything is added/removed.
