fix: Grafana dashboard 'no data' — datasource + Flux queries
- Fix datasource: bucket=smartcity, token=my-super-token, org=digitribe - Fix dashboard queries: filter by topic tag instead of _measurement (all data in measurement 'mqtt_consumer', type in tag 'topic') - Fix field names: temperature_c→temperature_celsius, luminosity→brightness_lux - Update dashboard to v3 with 15 panels (airquality, traffic, parking, weather, noise, light) - Update TODO.md and session_resume Tested: PM2.5 ✅, Temperature ✅, Vehicle Count ✅ via Grafana API
