fix(ui): use semantic color tokens for text foreground

- Replace hardcoded gray-900/gray-100 with text-foreground in EndpointSpeedTest - Add text-foreground class to Input component for consistent theming - Ensures proper text color in both light and dark modes
fix(misc): improve CLI version detection with path scanning
