Added a new section under the historical price table featuring quotes from ECB officials about Bitcoin, organized chronologically from November 2018 to January 2025. Each quote includes:

- Calculate min/max values dynamically from data instead of hardcoding

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
- Reduced historical data from 4,442 daily entries to 636 weekly entries
- This improves chart rendering performance and ensures all data up to current date is displayed
- Updated btcpoll.js to handle weekly data updates (updates same week or adds new week)
- Added aggregate-weekly.js script for future data aggregation needs
- Data now properly displays from 2013-09-15 to 2025-11-09
