Leads submitted with role-based email addresses like admin@, info@, or sales@ are rarely real prospects but still trigger routing flows, waste rep time, and pollute CRM data.

Requested behavior: Allow admins to configure a blocklist of role-based email patterns. Any form submission matching those patterns would be filtered out before routing fires.

Why it matters: Reduces noise in the pipeline, prevents reps from chasing dead-end submissions, and improves data quality in the CRM.
