feat: Provide way to have a clean copy of the table

When copying directly from the website into tools like Atlassian Confluence the input for the Note messes up they paste result. <input> elements are not well handled.

<img width="939" height="274" alt="Image" src="https://github.com/user-attachments/assets/983010c0-4a5f-4958-97ea-cd3e11cd75df" />

I'd like to have a way to get a clean html table copy of the rendered subnet split.
