fix(cses): remove verdict poll loop from submit

Problem: The submit method polled for a verdict for up to 120s, but
verdicts are never displayed in cp.nvim by design.

Solution: Remove the poll loop and `SUBMIT_POLL_TIMEOUT` constant.
After a successful POST, immediately return `SubmitResult(success=True)`.
