feat(cses): implement submit via REST API (#299)
## Problem

CSES submit was a stub returning "not yet implemented".

## Solution

Authenticate via web login + API token bridge (POST `/login` form, then
POST `/api/login` and confirm the auth page), submit source to
`/api/courses/problemset/submissions` with base64-encoded content, and
poll for verdict. Uses the same username/password credential model as
AtCoder — no browser dependencies needed. Tested end-to-end with a real
CSES account (verdict: `ACCEPTED`).

Also updates `scraper.lua` to pass the full ndjson event object to
`on_status` and handle `credentials` events for future platform use.
