feat: enhance file upload progress tracking and user experience

Browse Source 
- Add detailed upload progress tracking with speed and time remaining
- Implement dynamic waiting messages during upload initialization
- Create utility functions for file size and speed formatting
- Improve progress bar UI with more informative status details
- Add interval-based speed and progress updates for smoother UI
