fix: chart.js legend error + smart cache for date-range queries

Browse Source 
- Fix forecast chart confidence band fill config (fill:'+1' → explicit target)
  to resolve 't.legend.handleEvent' TypeError in Chart.js 4.4.1
- Add getOrFetchRange() to cache.js: auto TTL based on data age
  (end date >10 days old → 24h cache, recent → 5min cache)
- Apply smart cache to 6 heavy endpoints: bi, bi/revenue, bi/strategic,
  providers, providers/failed, providers/trend
