Player/UI fixes:
- Sports (match) Highlights pane: move the toggle click-handler script out of
the always-false @if(false ...) legacy block so the "Highlights" button opens,
and emit videoId/isOwner with @json instead of {{ json_encode() }} (escaped
quotes crashed the data/tab/CRUD block once route keys became hashid strings).
- Progress scrubber knob (video + audio players): center on the track line with
translate(-50%, -50%); drop the margin-top hack that floated it above the line.
- Music player volume: give the slider wrap height so overflow:hidden no longer
crops the knob; add a subtle thumb shadow for visibility.
- Music language menu: cap height to available space above the header, sticky
header, internal scroll; keep controls from auto-hiding while the menu is open.
- Description box: re-check "Show more" overflow at every settle point (fonts,
images, rAF, tab reopen) so SPA autonext keeps the expand button.
Also bundles pending work: save-to-playlist button component, playlist/channel
views, PlaylistController + NasSyncService, and component-usage tracker updates.
