fix(server): update PR status test for new normalized fields

normalizeCheckoutPrStatusPayload always emits the full wire shape now
(number, repoOwner, repoName, isDraft, checks, checksStatus,
reviewDecision) — the workspace-git-watch test's toEqual assertion
still had the pre-PR-pane shape and was failing.

Update the expected object to match the actual wire contract.
