Update README quick-start and adjust tests

Add a Quick Start docker-compose snippet and simplify the Manual Setup instruction in README; also replace three screenshot assets. Update multiple audiobook component tests to match recent UI changes: adjust expected button/notification text (e.g. 'Sign in to Request', 'Request created!'), change selectors for close/interactive controls, add PreferencesContext mock, reflect processing overlay and pending/denied status behavior, and update skeleton loader count (8 -> 10). These edits keep tests aligned with the current UI and improve getting-started docs.
