fix: Improve Prefix Handling and Input Validation in Utility Functions

[ursulabauer]

Hi team,

I’ve addressed a couple of issues in the remove_prefix_from_names and normalize_len functions:

1. Fixed typos that caused unexpected behavior in specific edge cases.
2. Added input and argument validations to ensure the functions are more resilient to improper usage.
3. Improved error handling for better clarity when something goes wrong.

With these updates, the code should now be more robust and user-friendly. Let me know if there’s anything else I can refine!

• Tests
• Documentation
• Added entry to CHANGELOG.md
• Tried the feature on a public network
