MessagesFeeder

Debug-only feeder that generates synthetic text messages in a given conversation.

What it does:

1. Picks up to 5 members of that conversation that:

• exist in the Member table for this conversation,

• have at least one valid client in the Client table (is_valid = 1).

2. For those users it generates up to 10k text messages in total (max 5 users × 2000 messages per user).

Generated messages:

• content_type = 'TEXT'

• visibility = 'VISIBLE'

• status = 'SENT'

• sender_user_id = one of the 5 selected conversation members

• sender_client_id = a real, existing Client.id for that user (never null)

• text_body = simple synthetic text
