Maptext 2023 tweaks [NO GBP] (#76397)

## About The Pull Request

- In PR https://github.com/tgstation/tgstation/pull/76356 missed a few
bits of maptext around, such as shuttle signs and the supermatter. Small
text adjustments/fixes here.
- Large amount of feedback about the context tooltips. Increases size,
lightens default color as to not be too imposing.
