Match highlights: fullscreen landscape drawer (narrow + clear glass)

Native fullscreen paints only #ytpWrap and its descendants, so the Highlights
pane was invisible in fullscreen. On fullscreenchange the pane is now relocated
INTO the player (and moved back on exit), and CSS reshapes it into a narrow,
transparent right-side drawer:

- Blurred-glass background (Clear) + text shadows so it barely covers the match
  while staying readable; @supports fallback firms up the fill where
  backdrop-filter is unsupported.
- Width clamp(230px, 30vw, 360px) — the Narrow choice, usable on any screen.
- While open: player controls + gradient pull in to the video area (scrubber
  never hidden), coach caption stays bottom-left, and the Highlights button
  slides to the drawer's left edge so it stays tappable to close.
- Same pane/data/tabs/CRUD; windowed bottom-sheet behavior unchanged.

Note: iPhone Safari forces native <video> fullscreen (no custom UI), so the
drawer applies where element fullscreen is supported (Android, desktop, iPad).
