fix: ManageBook menu auto-selecting Book Info on long-press release

RecentBooksActivity was passing initialSkipRelease=false when opening
BookManageMenuActivity via long-press Confirm. The button release
event was consumed by the menu as a selection of the first item
(Book Info). Pass true to match HomeActivity's existing behavior.
