- Refactored Dockerfile to utilize build arguments for VITE environment variables, allowing for better customization during builds.
- Improved Nginx configuration to handle larger video uploads by increasing client_max_body_size to 5GB.
- Enhanced backend Dockerfile to include wget for health checks and improved startup logging for database migrations.
- Added validation for critical environment variables in the backend to ensure necessary configurations are present before application startup.
- Updated content streaming logic to support direct HLS URL construction, improving streaming reliability and user experience.
