docs: Update project documentation for web-based architecture and development environment

This commit enhances the project documentation by updating the `.cursorrules` file to reflect the transition to a modern web-based photo management application. It includes detailed sections on the development environment, specifying the PostgreSQL server and development server configurations. Additionally, the README.md is updated to include development database information and environment setup instructions, ensuring clarity for new developers and contributors. These changes improve the overall documentation and support for the project's new architecture.
