Refactor GitHub Actions workflow for staging deployment

- Introduced a new job for database deployment, including steps to install Rust, cache dependencies, and run Diesel migrations.
- Updated the existing porter-deploy job to include AWS credentials configuration and SSL certificate retrieval from S3.
- Enhanced the overall structure and organization of the workflow for improved clarity and maintainability.
