Add playlist support to downloader API and frontend

Enhanced the downloader backend and frontend to support playlist URLs for video info and downloads. The API now returns structured playlist information, allows selecting specific videos for download, and returns a ZIP file for playlist downloads. Updated OpenAPI types, removed deprecated parameters (start_time, end_time, playlist_items), and improved Content Security Policy handling in nginx. Refactored frontend to handle playlist selection and updated generated API models accordingly.
