This pull request improves the validation, customization, and feedback
of various form components and modals in the admin-x-settings app. It
also adds new components for user detail modal sections and modifies the
user type to allow null values for social accounts. Additionally, it
adds `dirty` props to some integration modals and a `data-testid`
attribute to the exit settings button. It also deletes an unused file.
