[Ruthie-FRC]

this is my first attempt to try to clean up herohours. please don't judge me if it sucks. if its good, I take all the credit.

This pull request introduces several improvements and refactorings across the codebase, focusing on Django admin actions, code cleanup, and enhanced documentation. The most significant changes include improved handling of check-in/check-out logic with more robust time calculations, addition of helpful docstrings in WebSocket consumer code, and code cleanup to remove unnecessary print statements and clarify intent.

Django Admin Logic and Features:

• Improved check-in/check-out logic in HeroHours/admin.py to use a consistent right_now timestamp and Django ORM expressions (F, ExpressionWrapper) for accurate and atomic updates to time-tracking fields. This also ensures that missing Last_In values are handled gracefully. [1] [2]
• Added the entered field when creating ActivityLog entries during check-in, check-out, and reset actions for more complete audit logging. [1] [2] [3] [4]
• Improved admin list display by using the @admin.display decorator for clarity and consistency, replacing deprecated short_description and admin_order_field attributes. [1] [2]

Code Cleanup and Refactoring:

• Removed unnecessary print statements and dead code from HeroHours/admin.py, HeroHours/forms.py, and other files to clean up console output and improve readability. [1] [2] [3] [4]
• Refactored import statements in HeroHours/admin.py and HeroHours/consumers.py for clarity and to remove unused or redundant imports. [1] [2]

Documentation and Developer Experience:

• Added detailed docstrings to serializers, WebSocket consumers, and observer methods in HeroHours/consumers.py to clarify their purpose and usage for future developers. [1] [2] [3]
• Improved help text and argument parsing in the bulk.py management command for better usability and error prevention.

Other Notable Changes:

• Added a DEBUG configuration variable to .env.example to clarify default environment settings.
• Fixed CSV export filename formatting in the admin action for consistency.

These changes collectively improve code maintainability, reliability of time-tracking operations, and the developer experience for both current and future contributors.
