Introduces functionality to send a welcome email with credentials to new users upon creation and allows admins to resend a reminder email (without password) to existing users. Adds email templates, UI options for sending emails, and improves user management interface with new actions and enhanced layout.
This commit has some further changes to text throughout the application. There are also some small fixes for text formatting. E.g. making sure that the small "helper" text under certain form fields is all consistent in terms of colour, font, etc.
