fix(e2e): enable SwiftShader for WebGL on Linux CI

Chrome 137+ deprecated automatic SwiftShader fallback for WebGL.
Without --enable-unsafe-swiftshader, WebGL context creation silently
fails on GPU-less CI runners, causing black views and test timeouts.

Also simplifies bug report generation: use raw userAgent instead of
parsed browser string, inline bugReport in addError, and trim the
E2E test to just verify the copy button appears.
