Add S.I.T. Course Certificate tile

[ajcoppa]

Just started with a nag if you haven't picked any course when you first ascend.

I figure most other uses will get noticed and used from maximizer directly so it doesn't make much sense to have a regular tile for the resources, but open to ideas.

this looks fine but please merge main in so that we can merge it directly now that we merged the trainset improvement :-)

Merged main and fixed the conflict 👍
