Add state enums and HomeLayout styling improvements

Introduced generated stateE15Enum and stateFdaEnum TypeScript types for both private and public API models. Updated HomeLayout to use a new CSS module for layout styling, and adjusted navbar centering logic. Commented out reset.css in index.html and made minor CSS cleanups.
