feat: Scan cards share the same UI

[g123k]

Hi everyone!

This is a big PR with changes to 39 files (new code + renaming).
⚠️ I haven't translated anything into English. It would be nice if you could do it.

What's new

• All scan cards share the same UI
• If a barcode was syntactically incorrect, there was simply no card, no error… (fixed ✅)
• In the code, there were some classes with duplicate names (fixed ✅)
• In the code, there was an unused "Thanks" state (removed 🗑️)
• My PR will ease the removal of the carousel (💣)

Side quests:

• The Hero animation works between the carousel / product page / gallery / details (cf video)

• From the carousel, the product page shows a minimize button:
   

• The Compare button on the scanner uses the correct icon:
   

Product found

The obsolete icon is visible from the carousel. Is-it useful (cc @teolemon?)

Loading

The animation is still used:

New product

Error (network)

Error (invalid barcode)

List of changes:
product_title_card.dart: Pass the heroTag to the picture + use the same layout for all cards (except in the onboarding, where the image is hidden)
smooth_product_base_card.dart: The base card for all scan cards + shared Widgets
smooth_card.dart: The Container is replaced by a Padding (faster)
product_compatibility_helper.dart: Help to format the score with at least 2 digits
strings_helper.dart: Code moved
app_navigator.dart: Provide the back button type for the product page
reinvention_page.dart: Nothing relevant - OnboardingText is moved elsewhere
edit_product_page.dart: A generic barcode Widget is now available
product_compatibility_header.dart: Not used anymore
product_image_viewer.dart: A fix for multiple Heroes animations
