OP seems to be hung up on what's on paper and not reality on this gal.
She shows good poise and willingness to hammer, but she's fought mediocre competition at best, a bit on the slow side, and seems like mostly a brawler/puncher. I also agree that being the Irish Women's Amateur Boxing champ doesn't carry the same level of prestige as say the Russian or American champion.
Plus she'd be quite undersized for 145 unless she stripped off 5-7% in bodyfat and then put on say 12lbs of lean mass...which would be a lot to ask for when she could more easily fill in to a 135lb role. She doesn't even fight at 145!
