Add scripts/pb-init.sh — an idempotent alpine sh script that authenticates with the PocketBase admin API and POSTs all required collection schemas (books, chapters_idx, ranking, progress, audio_cache, app_users) before any application service starts. 400/422 responses are treated as success so it is safe to run on every docker compose up. Wire pb-init into docker-compose.yml: - pb-init service: alpine:3.19, depends on pocketbase healthy, mounts script - scraper and ui both depend on pb-init via service_completed_successfully, guaranteeing collections exist before the first request hits app_users
