Serve documentation screenshots locally instead of hot-linking GitHub - #395

Every image on the docs site was loaded from a GitHub host at page render time: raw.githubusercontent.com, user-images.githubusercontent.com, github.com and cloud.githubusercontent.com. That made the site's imagery a live dependency on a third party, and cloud.githubusercontent.com is a host GitHub retired years ago. This commit downloads all 89 of those images into content/assets/images/ and repoints the references at them. Each file was verified by its magic bytes rather than by HTTP status, and its extension taken from the bytes, which is how the one github.com/.../blob/ URL serving an HTML page instead of an image was caught. Two images that were not on GitHub are included for the same reason: getting-started/editions.md used GitHub's newer extensionless attachment URL format, and release-notes/3_14_0.md hot-linked docs.tabulareditor.com for an image already present in this repository. Only articles whose sole change is the image reference are in this commit. Not fixed: the gif referenced by beta-18_1.md and beta-18_2.md returns 404 because the TabularEditor3/PublicPreview repository no longer exists, so it has been broken on the live site for some time. It is left pointing at GitHub rather than removed, since dropping it would delete content from a historical release note. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Every image on the documentation site was loaded from a GitHub host at page render time, across four of them:
raw.githubusercontent.com,user-images.githubusercontent.com,github.comandcloud.githubusercontent.com. That made the site's imagery a live dependency on a third party, andcloud.githubusercontent.comis a host GitHub retired years ago.This PR does one thing: it brings those images into the repository and repoints the references at them.

<page-slug>-NN.<ext>.How the files were verified
Each download was checked by its magic bytes rather than by HTTP status, and its file extension taken from those bytes rather than from the URL. That is how a
github.com/.../blob/...URL was caught serving an HTML page instead of an image, which had been rendering as a broken image on the live site.
