headers on left-hand-side not attached to paragraph block on right-hand-side

### Bug

Default OCR works well BUT layout is wrong when headers are on the left but paragraph(s) on the right.

I think this is a bug, it is remotely possible this is a feature request in disguise (or even user error).

The test files provided are created by me, based on some real physical paperwork I was scanning and OCR'ing. EDIT also see comment https://github.com/docling-project/docling/issues/3643#issuecomment-4760454950 attachments.

The original was a 3-color scan, I've provided 3-color and mono samples.

This bug report is about the layout (although this may be an interesting one for bold/emphasized text?)

### Steps to reproduce

Download attachments and run:

docling --to html_split_page INPUT_FILENAME

demo uses `html_split_page` for easy reviewing of problem.

## First Header

## Third Header

Just a regular paragraph, note header is to the left BUT right aligned. This paragraph is justified but to the right of the header. There should be a line below.

Term: Yet more text. Not a lot, just a few sentences. Really tempting to use Ipsum here.

AnotherTerm: I'm getting lazy. I may just copy and paste the rest to save me some time. I can't keep typing rubbish for ever.

AnotherOne: This is a long paragraph. Yep, I'm about to copy and paste here. I'm getting lazy. I may just copy and paste the rest to save me some time. I can't keep typing rubbish for ever.I'm getting lazy. I may just copy and paste the rest to save me some time. I can't keep typing rubbish for ever.I'm getting lazy.

LastOne: Yet more text. Not a lot, just a few sentences. Really tempting to use Ipsum here.

Just a couple of paragraphs here. A few sentences each, longer than I really can be bothered to type here. I'm really getting bored typing this. No, more, please!

This is a long paragraph. but shortened to get a single page demo.

Download the attached HTML and PDF samples, then run `docling --to html_split_page INPUT_FILENAME` to reproduce the misplaced header structure. Compare the generated output with the expected grouping in the issue; done means headers on the left are attached to the paragraph content on the right without disrupting other sections.
