Next-level pass for the video nebula, ALL scoped under a video-only .vwsh-nebula
class so the music wishlist's global wl-* styling is untouched (verified: no bare
.wl-* rules in the video CSS).
1. Cinematic expand — an open orb bleeds the show's poster as a blurred, hue-
tinted backdrop behind the season fan + glows the panel in the show's hue.
2. Season tags — each season tile stamps a bold 'S2' over its art so seasons
read distinctly instead of identical posters.
3. Richer episode tracks — every episode line gets a colored status dot
(wanted/searching/downloading/done/failed) + its air date.
4. Sort + count — a Recently added / Most wanted / A–Z sort (query_wishlist gains
a sort param) and a live 'N shows · M episodes' subheader.
Tests: +1 (sort ordering). Backend 101 passed. Movies tab + music side untouched.
