[veena14cs]

This PR fixes #2266 . This PR implements new design for Admin and User Pin Verification
Older implementation of Pin Verification UI was using PinView library which was not supporting RTL. To fix this we removed this library and created new UI as per the new mocks.

@veena14cs The UI does not look correct.

1. The label Administrator's 5 Digit PIN UI is different from that of admin_auth_activity.
2. In landscape mode the UI does not look in centre.
3. Toolbar shadow is not correct.
   

Also, suggest updating the screenshots in PR Description

@rt4914 I have addressed and updated the changes

1. Changed the UI keeping it consistent with admin_auth_activity.
2. Centered UI at the center in landscape mode.
3. Corrected Toolbar shadow in Tablet mode.

Updated screenshots in PR description. PTAL Thanks.
