Standardize headings, wording, and inline comments across tutorials

[jkrick]

Motivation

• Improve consistency and readability across multiple tutorial notebooks by standardizing section headings and inline prompts.
• Make user-defined parameter prompts and code comments clearer for readers and notebook users.
• Add consistent notebook separators and small formatting/admonition fixes to improve rendering and navigation.
• Fix minor typos and wording to reduce ambiguity when following examples.

Description

• Renumbered and standardized section headings (added numeric prefixes) across several tutorials including euclid/, simulated-data/, techniques-and-tools/, and wise/.
• Reworded user-facing prompts and parameter labels (for example replacing ## How large do you want the image cutout to be? with Set the image cutout size) and changed in-code comment markers from ## to # inside code cells for clarity.
• made small formatting changes to improve markdown rendering.
• No algorithmic or data-processing logic was changed; updates are documentation and formatting only.

This is a codex written PR that I reviewed on my fork and then copied here.
@jaladh-singhal @troyraen just tagging you so you know what I am messing around with.

Thanks, this will be an improvement. I just have some minor comments.

This file got messed up. Numbers are being added to some of the code comments as if they were headings and the actual heading numbers aren't sequential.

got it.
