After an OPDS download completes, show a prompt screen instead of immediately returning to the catalog. The user can choose to open the book for reading or go back to the listing. A live countdown (5s, fast refresh) auto-selects the configured default; any button press cancels the timer. A per-server "After Download" setting controls the default action (back to listing for backward compatibility). Made-with: Cursor
