M14.4: the pasted-PDF fuzz test accepts a paste that refuses out-of-range art

Browse Source 
pasted_pdf_never_panics failed at random (about one run in four at 256
cases): a mutated digit turns a curve coordinate like 245.18535 into
245018535, so the pasted art spans ~1e8 pt, beyond MAX_COORD, and
edit.paste rightly refuses it with "result would exceed the canvas",
leaving the document unchanged. The helper unwrapped that result. The
test is about never panicking, so paste_from_elsewhere now ignores an
Err from edit.paste, with a comment saying why.
