Replace GitHub Actions artifact with MinIO upload

- Removed actions/upload-artifact@v4 (not supported in Gitea)
- Added terraform show output to create human-readable plan text
- Upload both binary plan and text version to MinIO
- Plan stored at: s3://bucket/terraform-plans/repo/run-number/
- Uses existing AWS CLI with S3-compatible endpoint
