docs(web-console): fix stale http:// URLs — the console serves HTTPS on :47992

The punktfunk-web unit serves HTTP/1.1 over TLS with the host's own
self-signed identity cert, but several guides still told users to open
http://<host>:47992, which fails. Correct the scheme everywhere and note
the one-time browser cert warning in the canonical + SteamOS docs.

The RPM %post web hint was doubly wrong (http://<host-ip>:3000): wrong
scheme and wrong port — the service listens on :47992, not the :3000 dev
default. Also fixes scripts/web-init.sh, so the URL the SteamOS/Linux
installer prints at the end of setup is correct too.
