• resolves Fix the "#links" throughout #430

This PR is an attempt to fix as many broken links as possible following the conversion from our PDF-oriented workflow to our mkdocs-oriented workflow.

Converting from one massive file to a website left us with a lot of section links (links to heading anchors like [Utility](#utility) that need to be replaced with links to files [Utility](../reference/decision_points/utility.md).

By a quick search of the markdown content, I think there were over 500 such links to start. I believe I've fixed them all here.

Output from the python linkchecker tool:

Statistics:
Downloaded: 5.43MB.
Content types: 6 image, 94 text, 0 video, 0 audio, 10 application, 2 mail and 250 other.
URL lengths: min=15, max=899, avg=84.

That's it. 362 links in 362 URLs checked. 0 warnings found. 0 errors found.
Stopped checking at 2024-02-14 12:07:05-004 (50 seconds)

Once merged, this PR puts us into a "known-good" ground state for link checking as well. I submitted a separate PR #465 as a downstream dependency on this one that will add a linkchecker acceptance test workflow for all future PRs.

• prerequisite for Create link_checker.yml #465

Note Once approved, this PR should be squash merged rather than a normal merge due to the fact that the individual commits have almost no meaning as they're all intermediate work-in-progress fixes.

As I was fixing links, I also took advantage of some opportunities to eliminate the need for some file includes by just merging the included content into the parent file. Hence there are a few file changes that look like they're adding content to files (which technically they are), but those are offset by removing the files that originally included that content.

thanks so much for fixing all of these.
