🎨 Palette: [UX improvement] Enhance Prefect flow UX

[ruhdevops]

This PR adds small but impactful UX improvements to the 02_logging.py Prefect flow.

💡 What:

1. Added log_prints=True to the flow decorator.
2. Added a detailed Markdown docstring to the main flow.
3. Added a clear success message at the end of the flow.

🎯 Why:

• log_prints=True ensures that any print statements are correctly captured as logs, providing a better developer experience when debugging or monitoring runs.
• Markdown docstrings are rendered by the Prefect UI, making the flow's purpose and features immediately visible to users without reading the source code.
• The success message provides immediate, pleasant feedback that the process finished as expected.

♿ Accessibility:
By moving important information from source code comments to flow docstrings, we make it accessible through the Prefect UI for all users.
