Mangalord/backend/tests/api_admin_analysis.rs

//! Integration tests for the AI-analysis enqueue wiring: chapter upload
//! enqueues `analyze_page` jobs, and the admin backfill / force-reanalyze
//! endpoints. All gated on `analysis_enabled` (the `harness_with_analysis`
//! variant turns it on; the default harness leaves it off → 503).
