Refactor resend email util and simplify endpoint

Move resend email helper from app/api/resend/utils to app/utils, use a module-level RESEND_API_KEY env var, and update the Authorization header to use it. Update import in resend endpoint to the new path and simplify the root response to only return meta. Also apply minor README wording and link fixes.
