phone_number and agent_ring_to are normalized and must resolve to valid 10-digit numbers.

group_id must be a positive integer.

If is_scheduled=true, schedule_datetime is required.

Behavior:

Validates recipient IDs against existing contacts/contact lists.

Excludes invalid/empty phone numbers and stores only normalized destinations.

Inserts broadcast data in chunks for large recipient volumes.
