perf: smart refresh — quick updates price/F&G only, full scrape every 6h
- Quick Refresh button: updates price + Fear & Greed only (~2 seconds) - Full Refresh button: re-scrapes all on-chain data from LookIntoBitcoin (~2-3 min) - Background auto-refresh: quick every 15min, full only when on-chain data >6h old - Cached on-chain data preserved between quick refreshes - On-chain metrics only update daily anyway, no need to re-scrape every 15min
