Implement Document Upload Functionality for MinIO

[Q-Niranjan]

This pull request adds the capability to upload documents to MinIO, a compatible object storage solution. Key features of this implementation include:

1. A dedicated method for uploading files to MinIO.
2. Integration with the database to save relevant metadata.
3. Robust error handling to manage potential upload issues.
4. Adaptation of the current upload process to focus on MinIO as the primary storage backend.

This enhancement aims to improve our document handling processes by utilizing MinIO for scalable and efficient file storage.
