BHV-10720 : change input to don't have a focus css when press 'enter'

## Issue
Header: 'Enter' prompts temporary Focus on Input

## Problem
Original ux design is that input has a spoltight css style when input is blured
But, in the http://jira2.lgsvl.com/browse/BHV-10720, new requirement is requested.

## Cause & Fix
Currently, input has their own CSS class "moon-focused". It override spoltlight css as gray color when input is focused.
If input is blurred with enter key, 'moon-focused' is removed thus only spotlight css is remained.
So, after blur, I unspot the input which is spotted so that looks not-red.
