feat(config): add enable-awesome experiment to show custom ASCII art

- Add ENABLE_AWESOME experiment flag (45758820).
- Update settings schema and regenerate JSON schema.
- Implement config.isAwesomeEnabled() wrapper.
- Add 'matt' ASCII art and update Header component to use it.
- Add unit tests for the new flag.
