+Unified calendar sync.
   1. FF live JSON (nfs.faireconomy.media) → this week + next week  (actual values, precise)
   2. FF HTML scraper → weeks 3..N ahead                            (upcoming forecasts)
+  3. FMP API fallback → weeks 3..N ahead, only if step 2 got blocked (ForexFactory now
+     403s the scraper — likely Cloudflare) AND an FMP key is configured (services.fmp_calendar)
 Called by the background loop in main.py and manually via POST /api/eco/calendar-sync.
