[TWEAK] Runechat Color Preference and Species Dependent Organ (runechat) Removal (#26018)

* Reopens runechat color tweak.

Fully changes how the runechat color works with human mobs.

- Ties Runechat color to DNA (unchangable via scramblers, or other methods like DNA modifying)
- Runechat color is now a preference based thing and can be changed at mirrors.

* Linter mint

* Comment for comment's sake + Rerun cerestation CI/UNIT test because mouse ate a cable.

* augh

* reverts toml

* Fixes a SQL query, good for final review.
