KenM76andClaude Opus 5.5 ccb2565036 fix(forms): auto-sized single-line text fields fill their height, not 12 pt ...

An auto-sized (`0 Tf`) single-line text field drew at most 12 pt however
tall the box. Acrobat Reader draws it at the size the height gives (checked
black-box on a synthetic form: 30 pt and 60 pt fields); ISO 32000-2
§12.7.4.3 leaves the size implementation-defined. auto_text_size_by now
keeps the existing height / 1.15 size without the 12 pt cap, still shrinks
to the width and never goes under 4 pt, with the height bounded at 14,400
(MAX_AUTO_HEIGHT, the largest page side ISO 32000-1 Annex C recommends).

Multiline and comb auto-size keep their 12 pt cap: not yet checked against
Acrobat.

Tests: the forms unit tests now pin a tall box's size (they pinned 12 pt),
and an automation test fills a 30 pt field through form_fill and measures
the drawn text with text_find. All three fail with the cap restored.
