/**
 * Bridge epic — chains the AI CFO `upload`-mode flow's two API hops.
 *
 * The first hop (`extractPolicyDocument` → multipart POST to
 * `policy-documents/extract`) lives on the cardPolicy slice and is
 * shared with the manual `CardPolicyCreatePage`. The second hop
 * (`fetchCardPolicyRecommendationFromUpload` → JSON POST to
 * `ai-cfo/policy-recommendation-from-upload`) is AI-CFO only.
 *
 * The chain is gated on `policyDocumentExtraction.aiCfoAnswerId` being
 * populated — manual callers leave it undefined, so the bridge is a
 * silent no-op there.
 *
 * Splitting this off from `policyRecommendationFromUploadEpic` keeps
 * the wizard component a pure renderer: it dispatches
 * `extractPolicyDocument(files, answerId, chatSessionId)` once, then
 * subscribes to `cardPolicyState` lifecycle flags to drive its
 * "Extracting…" / "Recommending…" pill.
