feat(home): clarify 5chan is serverless app, use current hostname for share links

- Homepage infobox: merged copy into single line explaining app nature and download link
- Share links (Copy direct link): use window.location.origin instead of hardcoded 5chan.app
- Settings version link: use current origin
- FAQ: add 'Is 5chan just this website?' entry under Basics
- Remove pleb.bz from CHAN_5_HOSTNAMES
