Rework tvOS player controls and settings sheet

Replace the tvOS bottom action bar with Settings / Info / Comments /
Next / Close. Settings reuses QualitySelectorView (video, audio,
subtitles, speed); Comments opens TVDetailsPanel directly on the
comments tab; Close stops playback and dismisses.

Debug button is hidden by default and can be re-enabled via a new
tvOS-only Advanced Settings > Developer toggle.

Present the settings sheet as a fullScreenCover with a centered
material card, fix the "Normal" hyphenation, and restyle row selection
throughout the quality selector on tvOS: per-row rounded backgrounds
with focus tint + stroke, vertical spacing instead of dividers, and a
focusable speed-rate menu.
