Subject: Add video speed control and improve playback smoothness

Added a speed control dropdown in the timeline toolbar that lets users change video playback speed between 0.5x to 2x. The dropdown shows the current speed and offers preset options.

Made video playback smoother by:
- Using better timing for speed changes
- Improving video synchronization
- Reducing playback stutters
- Making speed changes more responsive

The speed control is now easily accessible while editing and works smoothly with all video clips.
