Subject: [PATCH] fix: switch audio to preload=auto when player opens or seek
 is triggered

preload='metadata' only fetches the header; every seek then requires a
fresh Range request and buffering delay. Switching to 'auto' lets the
browser start buffering the file immediately so seeking into it is fast.
Set both in togglePlayer (on open) and in seekToSection/jumpToDaySection
(in case the player was already open with the old metadata-only mode).
