DD would have still called her to witness. Nothing says she didn't
just add that she could see them. It wouldn't be the first time in the
book that someone has stretched the truth a bit.

" 'A Squib, eh?' said Fudge, eyeing her closely. 'We'll be checking
that. You'll leave details of your parentage with my assistant
Weasley. Incidentally, can Squibs see Dementors?' he added, looking
left and right along the bench. 'Yes, we can!' said Mrs Figg
indignantly." (OOP)

That testimony wasn't contradicted by anybody in a powerful wizarding
body. If it's anything like our courts, uncontradicted testimony
stands. I believe nobody contradicted Mr. Figg because they knew she
spoke the truth, unlike Idiot!Fudge, who just plain didn't want to
hear anything that might be favorable to Harry.

While a Squib may not be a wizard, they're  wizarding folk who can
live their lives in the magical world. Mrs. Figg doesn't, Argus Filch
does.  Heck, Mrs. Figg is in the Order of the Phoenix.
