Implement "Create account" page

[alex-anakin]

Overview

Implement a page that allows a user to input an email and start the process of creating an account.

Action Items

• The "Create account" button is disabled by default.
• Enable the "Create account" button when the input value is not empty (consider spaces as empty input).
• After clicking the "Create account" button validate inputted symbols in the client using a regular expression.
• If the inputted value is not valid email then show an error.
• If the inputted value is valid then check out if the inputted email is not registered in the VRMS system by sending a request to the back-end.
• If the inputted email is not registered then redirect to the temporary dummy page from Create temporary dummy page #321.
• If the inputted email is already registered then show an error. The error should contain a link to the "Sign in" page (or dummy page if it is not implemented).

Resources/Instructions

• The page should be implemented in the client folder client-v-04
• Please follow UI development guideline.
