Refactor testing setup to utilize Testcontainers for PostgreSQL isolation
- Replace pgtestdb with Testcontainers for improved test isolation and reliability
- Update test setup functions to spin up dedicated PostgreSQL containers for each test
- Ensure automatic cleanup of containers after tests to prevent resource leaks
- Modify documentation to reflect changes in testing methodology and benefits of using Testcontainers
