canvas year is properly synced with STATION_YEAR_OFFSET define (#95067)

## About The Pull Request
Passes the define to the UI via static data.

Works fine:

/>

## Why It's Good For The Game
We have defines for a reason, even if its a bit annoying, tsx files
should respect them as well.
## Changelog
N/A. unless your a downstream that changed the define number (Hi that's
me)
