fix: player float mode now works; add minimal player style

Float mode was broken because AudioPlayer was unmounted the moment
audioStore.active became true — exactly when the float overlay needs
to render. Fix: keep AudioPlayer mounted in float and minimal modes
regardless of audioStore.active; only standard mode shows the
'Controls below' message.

Adds a third 'minimal' style: a compact single-row bar (skip ±,
play/pause, seek, time) with no voice picker or chapter browser.
Voice picker and chapter button are hidden in the idle pill too.

Settings UI updated to show all three options with a live
description of what each style does.
