The keyboard focus indicator on the status bar controls and Welcome to PerfView content did not consistently meet the WCAG 3:1 contrast requirement.
This adds a 2 px, theme-aware keyboard focus outline to those controls and links.
- Meets the WCAG 3:1 contrast requirement in light and dark themes
- Adds regression tests for contrast, thickness, and control wiring
