feat: add ViewCounter enhancements and file upload progress tracking

- Improved `ViewCounter` with visibility-based view increment using `IntersectionObserver` and 50% video progress tracking.
- Added real-time file upload progress updates via Socket.io, including status and percentage feedback.
- Integrated `ViewCounter` dynamically into `ContentCard` and removed redundant instances from static pages.
- Updated backend upload logic to emit progress updates at different stages via the `EventsGateway`.
