Treat main and latest as embedded, drop the unreachable 10.11 fallback

An "embedded" default only helps fresh installs: every existing server has
"main" or "latest" saved and would keep fetching a moving branch ref
forever. Those values never named a version, they meant "newest", and the
newest that matches the installed plugin is now the embedded copy. A tag
or commit still resolves to jsDelivr.

This makes the 10.11 fallback unreachable ("main" resolves to embedded
before the guard), and it was already dead: it compares
JellyfinVersionAttribute.GetVersion() to "10.11" by equality while the
assembly declares "10.11.2". Remove it, along with the config page's
client-side copy of the latest-to-main rewrite.
