feat: enhance video streaming and transcoding capabilities

- Added support for video codec analysis and transcoding based on codec information. - Implemented new API routes for transcoding videos, allowing for dynamic quality adjustments. - Updated video player components to handle errors and fallback to transcoded versions if direct streaming fails. - Enhanced database schema to store codec information for media files. - Introduced a VideoAnalyzer utility for extracting codec details from video files during scanning. - Improved CORS handling in API responses for better compatibility with various clients.
