feat: show crawled document details and FAQ counts in Captain (#14863)

- Add a document details view that surfaces crawled content, source
metadata, and generated FAQ counts.
- Rename the document card action to open details and show the FAQ count
inline in the list.
- Return `responses_count` from the documents API efficiently and expose
document content in the show payload.
- Update related Captain copy to reflect the new details-oriented flow.
