- Added MinIO as a dependency in package.json.
- Updated FilePreview component to simplify file type checks.
- Refactored file removal API to delete files from MinIO instead of the filesystem.
- Modified file serving API to fetch files from MinIO.
- Changed file upload API to upload files directly to MinIO and store metadata in the database.
- Enhanced environment configuration to include MinIO settings.
- Updated file type utility to handle file extensions more robustly.
- Created a new utility for MinIO client configuration and bucket management.
