Send 404 immediately for known public requests (#11117)
Instead of further handling requests to public which causes issues like #11088, immediately terminate requests to directories js, css, fomantic if no file is found which is checked against a hardcoded list. Maybe there is a way to retrieve the top-level entries below public in a dynamic fashion. I also added fomantic to the reserved usernames and sorted the list. Fixes: #11088
