Known design changes:

• The shadow for the image view is shown to be #4D000000 in mocks but actually that was not working correctly. Now this color is exactly same to #B2B2B2 without transparency. So I used #B2B2B2 and its other transparent versions for shadow.
• The accessibility test fails when we show Administrator string but that is fine because the Administrator string is meant to be a secondary string and we don't want learner's focus on that string.
