This pull request improves the user management and Stripe integration
features in the admin-x-settings app. It adds a new `ChangePasswordForm`
component for changing user passwords, refactors the error handling and
response handling logic in the `StripeConnectModal` and `apiRequests`
files, and fixes a bug in the `UserDetailModal` component. It also
creates new files for the custom error classes and the response handling
function.
