feat(player): raise the playback speed ceiling off YouTube's limit

A single speed ladder fed both players, so the 2x cap that YouTube's
iframe API enforces also applied to Bunny and R2, which are plain <video>
elements the browser will play far faster. Pick the ladder per provider:
YouTube keeps 0.25x-2x, the native ones go up to 16x, where Chrome and
Firefox clamp playbackRate. The picker labels everything past 4x as
"no audio", since that is where the browsers stop pitch-correcting and
drop the audio track.
