fix(journey): websocket sync across devices + 404 redirect

- broadcastJourneyEvent now excludes by socket ID instead of user ID,
  so other devices of the same user receive real-time updates (#615)
- Routes pass x-socket-id header through to broadcast functions
- loadJourney handles 404 gracefully — redirects to /journey with
  toast instead of infinite spinner (#616)
