1.0 library + player settings: Jellyfin/Link/Files library with details panel, player gear, settings cards, host flag

Library: source switch, selectable cards with a details panel, one merged
Continue row, Latest grouped per series without re-releases, Link page with
previews and recent links, Files embedded. Player: gear popover in both
designs, progress line while controls hide, live hwdec. Settings rebuilt as
cards. State marks the host member (proto stays 9, unreleased); hosting
shows LAN invite addresses; window buttons in fullscreen. fadeThrough keeps
the outgoing view's state.
