Interface changes

This update primarily introduces small UI changes, notably the return of weapon icons, now featuring colored backgrounds. While a minor change, this is a harbinger of a larger UI rework. We’re testing the readability of this solution, and if it proves effective, it will become a key component of the new UI.

As with most updates, this one also brings some balance changes, including shortening the first two waves to 25 and 45 seconds, respectively.
