feat: Display story replies with attachment and context label (#13356)

https://linear.app/chatwoot/issue/CW-6394/story-responses-are-not-being-shown-in-the-ui
When someone replies to your Instagram story, agents in Chatwoot only
see the reply text with no story image and no indication that it was a
story reply. This makes it impossible to understand what the customer is
responding to the message looks like a random text with no context. For
example, if a customer replies "Love this!" to your story, the agent
just sees "Love this!" with no way to know which story triggered the
conversation. This PR fixes the issue by storing the story attachment
and adding a context label.
