First I want to commend you for not giving up on this and just getting rid of the cat and trying to root out the issue instead of dumping her. I could never do that myself but there are so many who would, I dealt with a cat that would attack you so badly with her claws it required medical attention and stitches on more than 1 occasion and this went on for years trying various ways that didn't involve amputating her toes. We finally had to have her declawed. I see no point in doing it period, if you can't teach your cat where to and where not to scratch and your furniture is just so precious you don't even want the chance of it getting scratched you don't need to have a cat(or any animal, all can cause scratches on furniture, floors, etc) but in this case this was last chance, declaw or euthanasia, vet told me that, and I don't just give up or won't put down a healthy animal. So I do know what you are going through in a way with an issue that just can't seem to be solved and keep happening long term. Especially when everything you are trying should work and doesn't. You get to the point of ripping your hair out.
She is young and something is wrong if she knows she isn't supposed to go there and is ashamed by it. Could she be having occasional issues getting to her box in time? That sounds like it might be a part of the issue if she did it 2 feet from her box, but if she had to climb through the box to get there then maybe no.
It sounds like you need a second opinion to see if they can figure it out, or you might be better off just keeping her out of the dining room if possible or putting the box right on top of where she is going(I think you said you tried that though.)
Type up a synopses of what has been happening, even printing this thread(if allowed, I know some boards are weird about that) and taking it in or going through the post and writing down what has happened and that should help the vet in figuring it out.
I wish you good luck on this and I hope you find the solution soon.
