Adds DELETE /api/v1/conversations/{cuuid}/messages/{uuid} for removing private
notes via the API. Uses a dedicated `delete-private-message` query/stmt
(separate from the generic `delete-message` used internally by continuity) so
only messages with private=true can be deleted — sent/incoming messages are
protected. Returns 404 if the message doesn't exist or isn't private.
Useful for API consumers that create private notes programmatically and need to
clean them up (e.g. replacing an outdated note before adding a new one).
