Add Deluge integration; revamp admin Jobs & Logs UI

Introduce Deluge download client service and tests, remove obsolete rdtclient service, and update qbittorrent integration/tests and download-client interfaces/manager. Large UI refactor for admin pages: Jobs and Logs were redesigned to be responsive (mobile card views + desktop tables), improved headers, dialogs, controls, and better status/detail rendering. Also updated DownloadClient components (card, management, modal), organize-files processor, audible-series integration, and related unit tests to align with integration changes. Minor UX and accessibility tweaks, cron handling/validation adjustments, and a few formatting/cleanup fixes throughout.
