Compress various static assets

Compress static assets to help load faster. Noticed this from Lighthouse on main page as well as others. I think the correct course is using nginx but failed to get it working with the current setup due to the current websocket + systemd + node flow:

Ultimately, this will need to be played around with on a test server instead of the main as it might take awhile to get right.
