TermData should be generated preStart

[KevinWu098]

Similarly to how we generate the fuzzy search data, one convenient way to keep our term data updated would be to have it fetched from AAPI at preStart.

Fetch calendar and term data from the AAPI at preStart, write it to a generated file, then consume it via a new TRPC route on the frontend.

... perhaps building catalogue should be generated prestart as well 🤔
