Fix/dag table a11y issues

[RamonEspinosa]

Description

This PR solves some accessibility issues in the DAG Table.

The problem

I ran an audit using Wave and found that there where some elements that had no text nor labels assigned. This is a problem for users who have low visibility issues and prefer to use screen readers because, provided they stumble upon one of these elements, the screen reader will skip the element, resulting in a bad user experience.

The solution

1. Added aria-label attributes to input elements that had no labels.
2. Added a VisuallyHidden component to render text for screen readers.

Thanks for the fantastic improvement! I didn't know the Wave, but it looks very handy :)
