feat: add space weather + AI watch feeds, fix data binding issues

- Add space_weather source (NOAA SWPC: Kp index, X-ray flux, alerts)
- Add ai_watch source (arXiv cs.AI/LG/CL, HuggingFace, lab trending)
- Fix RSS circuit breaker: per-feed source names prevent cascade trips
- Fix displacement field: internally_displaced (was reading idps)
- Fix energy prices: handle nested oil.brent/wti structure
- Fix climate anomalies: use temp_anomaly_c and precip_anomaly_pct
- Fix news ticker: add feed_name to source fallback chain
- Remove defunct Reuters RSS feed, update War Zone URL
- Disable HTML caching for dev-friendly reloads
