Fix price table display by using closest-match dates and API fallback

Browse Source 
The price table was not displaying because of two issues:
1. The Bitfinex API was returning 403 errors, causing the entire get10yr() function to fail
2. The code was looking for exact date matches in weekly historical data

Changes:
- Add try-catch around API call with fallback to latest historical data
- Replace exact date matching with closest-date algorithm to handle weekly data
- Table now shows 10 years of historical price data with percent changes
