Image adjustments 2026

This ended up being a much bigger pull request than planned.

Main goal: get the margin figures lined up properly, and deal with some page fitting.

Other things that happened:

• there is now a built-in pagebreak utility, so I got rid of my own hack for this. We now specify page breaks in the publisher files.
• I got rid of a lot of the "In the following exercises" intros to exercise groups. In anticipation that we might one day want everything coded for WeBWorK, this makes sense, since the introduction gets written into every problem in the interactive version
• there were some tables in the Taylor poly and series sections that made more sense as align* so I made that change
• I cleared out some exercise content that doesn't look good in PDF (it's still there in HTML and WeBworK)
• I fixed some bad boxes (but not all! there are hundreds...)
• Other improvements to page breaking, especially in exercise sections

No changes to content, except for a few typo fixes.

@APEXCalculus here is the current PDF build. This is what we get direct from PreTeXt, with no further adjustments.
(Disclaimer: I had to submit one pull request to PreTeXt to get page breaking in exercises, so that won't work until that change is merged)

When you have time, please have a look, and please be as picky as you like about placement of figures, page breaks, etc.

I'd like to get the PDF to a point this summer where you're willing to do an APEX 5.0!
