feat: migrate storage system from filesystem to S3-compatible storage

- Implemented S3 storage integration, replacing the previous filesystem storage.
- Added automatic migration script for existing files from filesystem to S3.
- Updated Docker configuration to include MinIO for local S3 emulation.
- Removed obsolete filesystem-related code and endpoints.
- Enhanced upload and download functionalities to utilize presigned URLs for S3.
- Updated environment configuration to support S3 settings.

This change significantly simplifies file management and enhances scalability.
