Add "Download All in ZIP" feature for session downloads

Introduce automatic ZIP file creation and management for session-based downloads. - Server: Add endpoints to serve and provide info about session ZIPs; VideoService now updates ZIP after each MP3 download with user-friendly filenames. - Client: Add "Download All in ZIP" button with loading state and ZIP info; trigger browser download via JS interop; responsive and styled UI. - API: Extend service interfaces for ZIP download/info; add SessionZipInfo model. - Docs: Update SESSION_MANAGEMENT.md with ZIP workflow, endpoints, and UX details. - Robust error handling and logging throughout.
