video: fix detail reload (music router clobber) + reliably show missing episodes

Reload bug: music's router boots first, rewrites an unknown /video-detail/... URL
to /dashboard, and my init read the already-changed URL (no restore) AND dispatched
open-detail before video-detail.js was listening (empty page + stray back button).
Fix: capture the path at SCRIPT-EVAL time (before music boots) and DEFER the
restore to a macrotask so every DOMContentLoaded handler is registered and music's
initial routing has run — then re-assert the real URL. Reload/deep-link now restore
the exact item.

Missing-episodes bug: the full-episode-list cascade only ran via the lazy refresh,
which was gated on ART being missing — so a show that already had posters/logo
never pulled its episode list (stayed owned-only). Added shows.episodes_synced
(schema v5): the worker sets it after a full cascade; show_detail returns it; the
lazy refresh now triggers when NOT synced, so owned + missing episodes populate.
