feat: 4223 - comparison page for 3 random products on dev mode (#4444)
* feat: 4223 - comparison page for 3 random products on dev mode New file: * `compare_products3_page.dart`: Test page about comparing 3 products. Work in progress. Impacted files: * `attributes_card_helper.dart`: refactored introducing two new reusable methods * `nutrition_container.dart`: refactored introducing one reusable getter * `product_cards_helper.dart`: refactored introducing one new reusable method * `user_preferences_dev_mode.dart`: added an item computing 3 random products and showing the product comparison page * feat: 4223 - stupid lint check part 4 * feat: 4223 - access to boosted comparison from list page via dev mode Impacted files: * `product_list_page.dart`: slightly refactored the app bar text in selection mode, in order to have several possible actions; replaced the FAB with an explicit (?) "multi-select" button; added a "boosted comparison" icon button when 2 or 3 products are selected; added a "ranking" icon button * `user_preferences_dev_mode.dart`: added a dev mode flag for "boosted comparison" (sic) * feat: 4223 - minor warning fix * feat: 4223 - now displays item actions in a "more..." menu New file: * `product_list_item_popup_items.dart`: Popup menu items for the product list page, for selected items. Impacted files: * `product_list_page.dart`: now displays item actions in a "more..." menu * `product_list_popup_items.dart`: minor refactoring
