* Fix#304: normalize server URLs before connecting
Prepend http:// when no scheme is present and strip trailing slashes
for all server types. For Jellyfin, additionally strip /web/index.html
and /web path suffixes that users copy from the browser URL bar.
Normalization is applied in ServerManager.connect() on the by-value
parameter, so stored config is never mutated.
