kelmensonj/Warzone-SBMM-APP-Much-Improved ? reverse-engineered prompt

I want you to clean up and rebuild this Warzone SBMM scraping app so it actually works again with the current COD Tracker site.

Keep the same basic idea, a simple desktop app where I can start a new experiment or load an old one, then choose what data to collect. I want buttons or controls for grabbing leaderboard data, lifetime stats, recent matches, individual player profiles, and also player data from a group of matches or from players connected through a few match depths. It should save progress automatically so I can stop and continue later without losing anything, and fill in missing data when I resume.

Make the code much easier to understand than the old version, and if the current website layout has changed, update the scraping logic to match it. If you need to check current docs or site behavior online, do that. Please keep the GUI simple and functional, and make sure the results can be exported cleanly, like to CSV or a similar table format.
