Replace BookItem tiles with a plain ListView of tappable text rows
no dividers, and tighter padding than a ListTile so more of the 66 books fit on screen. All book names and chapter counts which are hardcoded literals in the widget tree can come from bookIdToFullNameMap and bookIdToChapterCountMap, so they can't drift from the database. Because a list row is full width, the abbreviations e.g Deut etc become full book names, matching the reader's title bar. Tapping a book still opens the same ChapterChooser overlay, and single chapter books still skip it.
Also fix a bug, there is a missing dispose() for _chapterNotifier.
