feat(simulator): real-time (1s), fix ENABLE_PULSAR, add Pulsar/Redpanda publish, fix InfluxDB URL

- Change INTERVAL to 1s for real-time sensor data
- Fix ENABLE_PULSAR comparison (accept 'true'/'false' strings)
- Add publish_pulsar() and publish_redpanda() functions
- Fix InfluxDB URL (smart-city-influxdb instead of digital-twin-influxdb)
- Add docker-compose.yml with simulator service
- Add redpanda config and start script
- Add session_resume_2026-05-05.md
