Add email validation in initial installation

[boscosylvester-john]

Fixes #7337

Short description of what this resolves:

This PR adds email validation for the fields 'Contact Email' and 'Trusted Email' in the patient's Demographics section. Through this, we can remove the responsibility from users to add email validations to their required fields. As email validation is a common feature and as emails are key in contacting the patients, this validation is essential.

After update:

Changes proposed in this pull request:

1. In database.sql script, update the INSERT statements for layout_options table where form_id is "DEM" and field_id is either "email" or "email_direct", to include the value for validation field as "email".
2. In 7_0_2-to-7_0_3_upgrade.sql script, add UPDATE statements to update the value of validation field to "email" where form_id is "DEM" and field_id is either "email" or "email_direct"

@boscosylvester-john What are your thoughts on addressing existing installation data?

[boscosylvester-john]

@adunsulag Existing installations could be updated using the upgrade script 7_0_2-to-7_0_3_upgrade.sql
I have made the required changes in the upgrade script as well
