Two fixes:
1. handlePlayPause: add explicit requestAnimationFrame(updatePlayhead)
after setIsPlaying(true) to ensure RAF starts immediately.
2. handleEditSectionInTab: add setCurrentTime(0) to reset playhead
to section start. Without this, currentTime may be outside
the section's timeline range (e.g. from main session playback).
