When a customer responds to a bot's interactive prompt (input_select,
input_csat, form, input_email) from the widget, the response shows up in
the Chatwoot agent UI but is not reflected in the linked Slack channel —
Slack only ever shows the original question. This happens because the
widget submits the answer as an UPDATE to the original message (writing
`content_attributes.submitted_values` or `submitted_email`), but the
Slack hook only listened to `message.created`, so updates were ignored.

### How to test
1. Connect a web widget inbox to a Slack channel.
2. Trigger each bot message type (input_select, form, input_csat,
input_email) in a conversation.
3. Submit responses from the widget.
4. Verify each response now appears in the Slack thread, appended to the
original bot question.
