Replaces legacy email/SMS logic with a new IComService abstraction using the ProcessWeb Mailer API for all outbound communication. Removes FuchsFdsEmail, FuchsEmailService, IEmailService, SmtpAccountSettings, and FuchsEmailSettings. Updates controllers to use IComService. Refactors appsettings.json to use a new "Mailer" section. Adds ProcessWebComSettings and a stub for secret management. Removes OCORE.sms.SMS77 and direct SMTP/MailKit usage. Cleans up solution file references to OCORE projects.
