* fix(audit): an applied redaction at the end of a line is not a faux redaction

After Apply Redactions removes text at the end of a line, the line keeps a
TJ adjustment where the text was, and the box of the line still spans it.
The audit compared the redaction box with that box: at the end of a line
it covered more than 40% of it and the words left beside it were reported
as covered text, on a correctly redacted file. In the middle of a line the
gap was usually too small to cross the threshold.

Text lines now also give the boxes of the words they draw (`ink`: glyphs,
without spaces and TJ adjustments), and the audit measures how much of
those words a cover hides. A real cover over text that is still there is
found as before.

doc_audit_redactions also reports its rectangles in top-left-origin points
like comment_list and doc_info; they were in PDF user space.

* fix(audit): leave the rectangles of doc_audit_redactions in user space here

Reporting doc_audit_redactions rectangles in top-left-origin points is a
separate subject from the false alarm this branch fixes, and on its own it
made the tool and `pdfcraft-cli audit` disagree on the same file: the CLI
still prints PDF user space. Take it out of this change; the tool and the
CLI can move together in their own change.

* fix(edit): word boxes span whole words when glyphs run backwards

With a negative font size or a negative horizontal scale (Tz), each glyph
advances backwards along the text matrix, and the box of a word kept only
its first glyph: the end of the word was compared with a start that had
already moved past it. A word box is now the union of its glyphs whichever
way they go, and a TJ adjustment ends a word past 0.2 em of the scaled size,
whatever its sign.

* fix(audit): a cover over a short value after a long label is still found

Measuring a cover on the words of a line alone missed faux redactions main
found: a long label followed by a short value hidden under the box is less
than 40% of the line's words. A cover now also counts, as before, when it
hides 40% of the line's box and at least half of one word still drawn; a
cover over the gap an applied redaction left, with no word under it, still
does not. The audit README states both rules.
