Add initial project structure with Docker setup, SOLID principles, and video player implementation

- Created .gitignore to exclude logs and build artifacts.
- Added Dockerfile and docker-compose.yml for containerized deployment.
- Implemented a video player following SOLID principles with classes for video source, audio control, and volume meter.
- Introduced interfaces for audio, video source, and volume meter to ensure adherence to Interface Segregation Principle.
- Developed main entry point and HTML structure for the video player application.
- Included TypeScript configuration and package.json for project dependencies.
