Add comprehensive unit tests for homepage components and utilities

- Introduced unit tests for homepage components: `QuickStartCode`, `Header`, `DemoCredentialsModal`, `AnimatedTerminal`, `CTASection`, and `StatsSection`.
- Added utility tests for `chart-colors` including opacity, palettes, and gradient validation.
- Mocked dependencies (`framer-motion`, `react-syntax-highlighter`, `DemoCredentialsModal`) for isolated testing.
- Verified accessibility features, animations, and interactive behaviors across components.
