Subject: [PATCH 1/7] Switch portfolio snapshots from ETH to USD denomination

- Add database migration (003_usd_networth.ts) to add usdValue column
- Update cron job to fetch ETH/USD rate and store USD value in snapshots
- Update frontend to use usdValue directly without conversion
- Show chart for all currency settings (not just ETH)
- Format chart tooltip values as USD
