Really, Memory Beta? Several novels and still no one has given poor Seska a surname?
I have to do everything myself.
I think we pretty firmly established that they didn’t give her name much thought. At any point in her development.
I firmly reject the idea that she attended Starfleet Academy in any capacity. That does not fit with her personality (as a Bajoran or a Cardassian) or what we know of her cover story. Somebody was dreaming.
I also have to laugh at the caption below her photo. “Seska in her true Cardassian form.” If by “true Cardassian form,” you mean in the process of restoring her Cardassian DNA, then yes. Sheesh.
