Subject: [PATCH] fix: use correct nested biz node structure for interactive
 messages

Changes the biz node from flat structure (biz > native_flow) to nested
structure (biz > interactive > native_flow) as used by Pastorini/Astra-Api.

Structure:
- biz: {}
  - interactive: { type: 'native_flow', v: '1' }
    - native_flow: { v: '9', name: 'mixed' }

This fixes error 479 that was breaking all interactive messages.
