Pairlist-config in Webserver mode does not work (likely since ccxt moved the columns around)

FreqUI Version

• Version of freqUI: 1.2.5 (Available in the top right corner of the UI)
• version of freqtrade: works in 2024.7.1 does not work in 2024.8.1 and the current dev in docker, and in the current dev in bare metal too

Describe the bug Frequi webserver points likely to the wrong column since ccxt moved from name to classname to point to lowercase exchange names

To Reproduce Steps to reproduce the behavior:

1. Go to pairlist generator
2. select volumepairlist and for example binance (which will show up as capital B Binance)
3. See error

Expected behavior change back to lowercase versions (binance instead of Binance)

ps: thanks to Nin on the freqtrade discord for reporting this bug!

Nice spot - i wouldn't blame ccxt for it though - it's the changes i made for list-exchanges (to have it look nice) which broke this, as the meaning of exchange.name changed.
