- budget page: guard spend bar against missing/zero ceiling (no NaN width);
show an explicit "no ceiling set" state. Add pure budgetUsagePct() helper.
- job detail: replace silent live/poll toggle with an explicit stream-mode
badge (Live vs Polling) so operators see when SSE degrades to polling.
- fleet-client: extend patchJob to carry optional checkpoint/blockedReason
matching the server PatchJobSchema; add FleetCheckpoint type.
- tests: unit cover budgetUsagePct + patchJob checkpoint forwarding; e2e
asserts the polling indicator appears when the stream is unavailable.
- ci: add a Gitea Playwright e2e job that runs the fleet control-plane specs.
