Update app.py

Key Changes:
Function Extraction:

Extracted logical sections into functions like display_header, get_user_inputs, generate_and_display_wordlist, display_wordlist_statistics, and analyze_wordlist_security for better modularity.
Error Handling:

The error handling around wordlist generation has been made more consistent and clear. This ensures that any issues are immediately caught and communicated to the user.
Main Application Structure:

Created a main function to organize the flow of the app more cleanly, which improves readability and maintainability.
Performance:

Minor optimizations in the code structure and making sure that repeated actions are properly encapsulated within functions.
This should help with readability, maintainability, and extendability. Let me know if you need any more specific changes or further improvements!
