patient-ssapp email syntatic validation

[joaoluis-pdm]

The syntax of the email that the patient gives on signup should be validated.

(Meeting 2022-01-25 - email validation flow could be done after the pilot).

The email syntax is already being validated at the patient-ssapp, since the first working version, because:

• the signup form already uses <input type=email ...> field
• the https://github.com/PharmaLedger-IMI/ctr-workspace/blob/cc983e7a6a30019249427413a1c7809d3dbc08f7/ctr-patient/pdm-web-components/src/components/form-validate-submit/form-validate-submit.tsx already invokes checkValidity and reportValidity on the form DOM element.

So the patient would need to bypass the browser's validation to submit an invalid syntatic email.
