Closes audit #3 — PlayerController gains toggleShuffle / cycleRepeat
methods backed by Media3's Player.shuffleModeEnabled +
Player.repeatMode. PlayerUiState surfaces both via a new
shuffleEnabled flag and a RepeatMode enum (OFF/ALL/ONE) mapped
from Media3's int constants.
NowPlaying's BottomActionsRow grows two IconButtons: shuffle
toggles (accent when on, muted when off) and repeat cycles
off → all → one → off (Lucide.Repeat ↔ Lucide.Repeat1 swap;
accent when not-off).
PlayerViewModel exposes the two new methods as thin pass-throughs
matching the existing transport pattern.
