Add Contact or Company to Blocklist

Adds a contact or an entire company to your blocklist so they are excluded from outreach. Use scope 'contact' to flag an individual via a structured lookup, or scope 'company' to flag an organization by its LinkedIn company ID. The operation is idempotent and accepts an optional reason for your records.
