fix: fetch full interaction body per-id (list endpoint omits response)

GET /interactions returns response_chars but not the response body
to keep the listing lightweight. The batch extractor now lists ids
first, then fetches each interaction individually via
GET /interactions/{id} to get the full response for LLM extraction.
