Code examples on four pages (debug-area, background, border, rounded-corners) are now included from the QuestPDF.DocumentationExamples tests instead of being copied by hand, so the code on the page is the code that generates the image next to it.

How it works

• In the tests, the shown code is marked with #region docs:<name>.
• tools/export-documentation-snippets.cs (QuestPDF repository) exports it to docs/snippets/, runs the examples and refreshes the images on pages that include snippets.
• Pages include the code with <<< @/snippets/<name>.cs{lines csharp}; the llms.txt plugin expands it, so the .md versions contain the full code.
• The Update examples workflow runs the export in CI and commits the result, so no local copy of the QuestPDF repository is needed.

Also in this change

• Images regenerated from the current library (e.g. the placeholder icon and text rendering changed since the old images were made).
• Image alt texts describe the result instead of "example"; the styling moved to an example class.
• .Shrink() is now visible in two examples where the image depends on it.
• The rounded-corners table uses fixed data instead of random placeholders, so its image is reproducible.

Closing in favour of QuestPDF/QuestPDF#1493, which exports the code snippets and images with a different approach.
