Feature: Add Dashboard Base URL Configuration

[pyob-bot]

Summary of Changes

This pull request introduces a new feature to src/pyob/autoreviewer.py by adding the ability to configure a DASHBOARD_BASE_URL. This constant is derived from the environment variable PYOB_DASHBOARD_URL and defaults to http://localhost:8000 if the environment variable is not set. This change allows for flexible deployment settings, making it easier to switch between different environments without altering the codebase.

Technical Impact

• Environment Configuration: The application can now dynamically set the dashboard URL based on the deployment environment, improving usability across various setups.
• Flexibility and Maintainability: By relying on an environment variable, the codebase becomes less dependent on hardcoded URLs, fostering easier maintenance and adaptability.
• Backward Compatibility: Existing functionality remains unaffected as the environment variable is optional, and the default local URL is preserved.

No additional dependencies or external services are required for this feature. It enhances the application’s deployment flexibility, particularly useful for situations where the dashboard URL varies between development, testing, and production environments.
