Tailwind classes in OCaml

Consolidate GADT-based interface directly into Tailwind_html

Replaces verbose interface with type-safe heterogeneous list API. Removes separate Tw module and integrates all GADT functionality into Tailwind_html. Updates all examples to use consolidated interface with succinct ~styles parameter.
