[BUG] MCQ Asterisk Character Breaks Message Rendering

[matKlju]

Bug description:
MCQ node does not render “Message to client” when the message contains an asterisk *.
When an MCQ message includes an escaped asterisk, DataMapper fails while processing:

/services/hbs/bot_responses_to_messages

DataMapper error:

Request: {method: POST, url: /services/hbs/bot_responses_to_messages, params: {}, query: {}, body: {"data":{"authorLastName":"","buttons":[{"id":"1","title":"Jah","payload":"#service, /POST/services/active/mcq_test_mcq_1_0"},{"id":"2","title":"Ei","payload":"#service, /POST/services/active/mcq_test_mcq_1_1"}],"chatId":"","botMessages":[{"result":"Do you need to use an \"\\*\" asterix with quotes or not?

Expected behavior:
MCQ “Message to client” should support * characters without causing DataMapper/HBS JSON parsing errors.
The message should render correctly in the widget, whether * is used as plain text or part of formatting.

Screenshots:

Additional information:
Likely escaping issue in the HBS/DataMapper response generation flow.
