bflatastic 5850000e41 Prepare grouped text with Ungroup's own form expansion ...

text/forms/expand.rs was a drifted copy of ungroup.rs. It is gone: text preparation now opens each
placement with crate::ungroup, so Ungroup and preparation share one implementation.

What the copy added is now in ungroup.rs: a Refusal that says whether the form itself or only
this placement is the reason (intrinsic) and whether a rename alone was the problem (renaming),
the shows_text result, merges_without_renaming, refusals for unreadable /Resources and /Group
entries and arrays with a non-number, a cap on resource counts and q nesting, a total size for
pattern copies, and ending an unfinished path with the form. Ungroup's newer behaviour stays:
names are read from the operand the renderer uses, so a surplus operand is renamed correctly
rather than refused; default colour spaces are compared with the page's; and a group blending
in DeviceRGB on a page that names no blending space is drawn inline, as Ungroup does, rather
than refused as the copy did.

What a form draws is now read within one decode allowance shared with the form itself, so a
crafted group can no longer make one Ungroup decode 64 MiB for each of 1024 nested forms. A
group whose content can't be checked is refused; for a form without a group, blend modes inside
don't matter, and content that can't be checked only means preparation can't tell whether it
has text (shows_text is None), which it reports.
