chore(env): finding 3 — remove dead CROWDIN_PROJECT_ID/CROWDIN_API_TOKEN/GOOGLE_CLOUD_API_KEY

These three vars are only read by GitHub Actions workflows and tooling/fonts
scripts that access process.env directly — never by app/server runtime code.
Removes them from the env schema (server.ts) and turbo.json globalEnv.
