Reformat markdown for ruff 0.16 and pin ruff in CI

[gomezzz]

Summary

• ruff 0.16 started formatting fenced code blocks inside Markdown, so ruff format --check . fails on pre-existing docs files. That turns the lint job red on every pull request, including the contribution-guidelines PR.
• Pin astral-sh/ruff-action@v3 to 0.16.0. The action otherwise resolves to whatever ruff is newest, so an upstream release can fail CI on unchanged code, which is exactly what happened here.

Scope

Markdown only, no Python touched. Every hunk is inside a ```python fence: quote normalisation, magic trailing commas, comment realignment, line rewrapping. No documented API, argument, or value changed.

Verified locally

• uvx ruff@0.16.0 format --check . clean
• ESA licence headers confirmed intact on every reformatted file (the check_license_headers job compares them byte for byte)

Test plan

• lint green
• check_license_headers green
• Contribution-guidelines PR goes green once this merges
