-- ============================================================
-- 035_interactive_messages.sql
--
-- Full support for WhatsApp interactive messages (reply buttons +
-- list messages) beyond the Flows subsystem.
--
--   1. messages.interactive_payload — the structured payload of an
--      OUTBOUND interactive message (buttons / list) so it round-trips:
--      the thread can re-render the buttons/rows we sent, not just the
--      body text. Migration 010 already added 'interactive' to the
--      content_type CHECK and the inbound `interactive_reply_id`
--      column, so no CHECK change is needed here.
--
--   2. quick_replies — reusable snippets (plain text OR a saved
--      interactive message) an agent can insert from the inbox
--      composer. Account-scoped, same tenancy model as automations.
