Fix security scanning issues for CI/CD

- Update AWS SDK S3 client to use BaseEndpoint instead of deprecated EndpointResolver
- Replace deprecated io/ioutil with os package calls
- Add proper error handling for unused err value
- Remove unused s3Client field from metadata Store struct
- Remove unnecessary type assertions for provider factories
- Remove unused outputFile variable

All security issues identified by gosec have been resolved.
