Latest system, installation of new system CRMv1.67.1 Assignment throws OutgoingEmailError if no default email account is configured

[1060778506]

Description: When assigning a CRM Deal, the system triggers send_notification_email. If no outgoing email account is setup (which is common in new installations), the entire transaction fails with frappe.exceptions.OutgoingEmailError.

Suggestion: The system should use frappe.msgprint or simply queue the email without throwing a hard exception that breaks the UI flow.
