fix(schedule): auto-create reminders when agent only writes schedule items

When schedule_create_item includes a start time and reminder intent, create the
matching h5_schedule_reminders row in the same tool call so 10:00 pushes are not
lost. Also reconcile Goose SSE request ids with the portal agent-run gate to keep
MindSpace chat streaming reliable.
