Add ROOTLESS_CONTAINER and request UI updates

Introduce ROOTLESS_CONTAINER env to opt out of gosu (replace /proc uid_map detection) and update entrypoint messaging; adjust app-start.sh and redis-start.sh to skip gosu when ROOTLESS_CONTAINER=true and warn on UID/GID mismatch only when applicable. Backend: include audiobook audibleAsin in admin requests response (mapped to asin) and pass baseUrl through test-flaresolverr endpoint to the FlareSolverr tester. Frontend: RecentRequestsTable and RequestActionsDropdown now surface asin, accept/passthrough annasArchiveBaseUrl, and add a "View Details" flow using AudiobookDetailsModal; admin page passes ebook baseUrl from settings. InteractiveTorrentSearchModal refactor: improved UX/UI, keyboard handling, portal/modal mounting, skeleton/loading states, formatting helpers, and richer result display. Tests updated to match changes.
