Rename and update Flet CLI documentation
f065f9d 
Replaces old CLI command docs (build, create, doctor, pack, publish, run) with new files prefixed by 'flet-' and updates their content for improved clarity and completeness. Updates all internal references and navigation to use the new filenames and command names. Also updates build.py to recommend 'flet serve' for serving web apps instead of Python's http.server.
