test(e2e): event log entries + restart persistence

smoke: jump (shared helper) + scan, then assert both events are in
GET /api/events with the newer one first, and that the EVENT LOG terminal
renders both T<turn> // <MESSAGE> lines. Idempotent across retries — asserts
on this run's own entries by turn/message, never absolute counts. state: the
latest five log lines come back identical (ids included) after the mid-run
container restart.
