Excessive log errors trying to obtain exchange rate data from Coindesk API

[dmullinsgithub]

In February 2025, the btc-rpc-explorer logs began displaying numerous errors when trying to obtain BTC exchange rate data using the Coindesk API (https://api.coindesk.com/v1/bpi/currentprice.json). The code attempting to use this API is located in btc.js

I created a fix for this by using an apparently new API from Coindesk (https://min-api.cryptocompare.com/data/price?fsym=BTC&tsyms=USD,GBP,EUR). Not sure if this is the best approach since I am not an experienced js developer, but it works. I have attached the modified btc.js (renamed to btc_ratefix_for_github.txt to allow it to be attached here):
