Refactor storage integration from MinIO to S3

- Removed MinIO client and related imports from various modules.
- Introduced S3 client and OSS integration for object storage.
- Updated all references to MinIO methods with corresponding S3 methods.
- Added new flowme table schema to the database.
- Adjusted upload and download routes to utilize S3 for file operations.
- Removed obsolete MinIO-related files and routes.
- Ensured compatibility with existing application logic while transitioning to S3.
