Impacted files:
* `app_en.arb`: added 2 translations (and fixed 1)
* `app_fr.arb`: added 2 translations
* `edit_product_page.dart`: added an item for "edit categories"
* `Podfile.lock`: wtf
* `simple_input_page_helpers.dart`: implementation for "categories"; refactored with an "in language" abstraction
