Refactor progress event handling in progress.js

- Moved the 'video:progress' event listener to be consistent with the RAF and timeupdate events.
- Ensured 'setBar' for 'loaded' is emitted during both RAF and video:progress events.
- Cleaned up the structure for better readability and maintainability.
