Update: I set up my daughter's email on EA.com and spun up a support case with her account. That support agent was able to find the profile the previous support agent said was gone, and move that progress over to the new profile. So her meager recent progress is restored, thankfully. Pretty annoying that the first support agent told me I was out of luck, though.
On a related note, the goodwill grant didn't grant any mints. So she lost the mints she had, and earning mints takes forever. That's probably the biggest setback from originally losing her progress.
