feat(plex): rich media info — info page, in-player info overlay, IMDb + cast photos

Backend (no migration): item_detail now also returns IMDb score + id/url (from the
Plex Rating/Guid arrays), content rating, genres, director(s), studio, tagline, and
cast as {name, role, photo}. New host-whitelisted /person-image proxy serves cast
photos from Plex's public metadata CDN (keeps third-party requests off the browser).

Frontend: reusable PlexInfo component in two forms — a full info page opened from a
card's 'i' button (history subview, art backdrop, Play/Resume + watch controls) and a
lean overlay in the player toggled with 'I' (video keeps playing). Two per-user view
prefs (faint backdrop, cast row) persisted in preferences. Mark-unwatched / clear-resume
cover the watched-reset gap. i18n en/hu/de.
