A line goes to the first level whose style it is in, so the same style
for two levels, or one within the size tolerance of the other, left the
later level empty without a word. The edit now refuses it, for the dialog
and automation alike, naming the two levels (CodeRabbit on #4560).

CodeRabbit on #4560:
- The bookmark titles are the document's text, so the edit now needs
copying permission as well as assembly, and Document::text_styles (the
dialog's samples) is empty when copying is withheld; the automation
text_styles tool already checked it.
- A heading went on to the next row whenever it was close below in the
same style, so same-style headings in two columns on staggered rows ran
together into one bookmark. A line continues a heading only when it lies
under it.
- Lines found their style by a scan over every style so far; they are now
indexed by font, weight, slant and quarter-point size, so a page with
thousands of styles no longer makes the scan quadratic.
Regression tests for the first two (each fails without its fix).

Bookmark options > New bookmarks from text styles... lists the styles the
document's text is set in (font without its subset tag, the size shown,
bold, italic, how many lines, a sample), the largest first, and takes one
style per bookmark level. Every line in a level's style becomes a
bookmark of that level under a new first "Untitled" bookmark, as from
structure; a heading set on several rows is one bookmark, and each goes
to the top of its heading.
The detection lives in engine::text_style_bookmarks on top of
edit::text_lines, reading each page top to bottom then left to right, so
two headings on one row stay two. text_styles and
bookmark_from_text_styles reach it headlessly, and the command
bookmark.from_text_styles opens the dialog. OutlineEntry gets an
optional top for the /XYZ destination; structure bookmarks keep theirs.
