Refactor Terraform init to use backend-config flags

- Updated backend.tf to use partial configuration
- Modified workflow to pass backend settings via -backend-config flags
- Follows Azure-style pattern with environment variables
- Improves flexibility and keeps configuration out of version control
- Required secrets: MINIO_ENDPOINT, MINIO_BUCKET, MINIO_STATE_KEY
