[jerader]

closes AUTH-972

Overview

Wires up form errors and updates the copy.

Test Plan and Hands on Testing

Create a protocol and add a transfer step. have it transfer from 2 wells into 3 wells and see the form error which should render immediately at the top of the form.

Changelog

• add the onBlur and onFocus fields to the dropdownMenu component so the errors render as expected in PD
• add the hasBackgroundError boolean to input field for a form error in PD
• update copy
• fix bug with the errors not rendering immediately

Risk assessment

low
