List the Instagram account's own posts, for the post share

GET 
/api/conversations/:conversationId/instagram/posts

MEDIA_SHARE sends one of the business's own published posts into the DM and Instagram draws it there. Meta's condition is one sentence — "Your business must own the media you send in the message" — and listing what THIS account published is what makes every offered id owned by construction.

There is deliberately no search parameter and no id field anywhere in this feature: a typed id would be an agent guessing at an ownership rule they have no way to check, and Meta answers a wrong guess by refusing the send.

Authorized through the conversation view ability. A conversation that is not Instagram is a 404. An account that has published nothing returns 200 with an empty data — a true, self-explaining state with nothing to configure. A Graph refusal is a 422 carrying Meta's own reason in detail.
