Unique user agent per window & Minimal interface

[UnlikelyBuddy1]

• Updated the list of user agents to include recent devices (2023).
• Instead of completely removing user agent client hints, we keep them and use a different one for each window.
• Add the option for a minimal interface which doesn't take horizontal space away from the game window.
