I'll check the rest later, for now I've put some preliminary review.

nit: I though we had a PasswordInput component in the existing UI lib. Since we're using components from that library withing the file, could we use it as well?

[malinskibeniamin]

Let's use this for now, the reason being is that this is a new component that uses tanstack form, I don't want to mix it up with the old implementation from component library. Also when using AI LLMs it doesn't work well with UI library because it does not have enough context of our internal API.

nit: I'd still prefer to stay consistent with the upper-level mobx classes to handle the logic and remove it with MobX later on. I think we would benefit from consistency.

Agree, I am trying to move quite fast, so I had to resort to this to ensure the title is set properly, otherwise it was overriding it.

The problem I have is that with MobX decorators and class-based components or observer pattern I will never get out of the legacy/tech debt we have today, so I decided this is the best we can do for now.
