Add support for new Knowledge panel actions and ensure new actions do not crash the app in the future

[teolemon]

Problem

• We added some more actions server side (live in production): https://github.com/openfoodfacts/openfoodfacts-server/pull/7304/files
  • action_add_origins
  • action_add_packaging_image
  • action_add_ingredients_image
• It seems they are not supported yet by the app, although the API was meant to be evolutive (eg: it provides the button name, and the editing view can be inferred from the action)
• Add support for those new Knowledge panel actions in a way that ensures new actions do not crash the app in the future, and are supported automatically

Future provisions

• action_add_basic_details
• action_add_portion_size
• action_add_nutrition_image
• action_refresh_ingredients_image
• action_refresh_nutrition_image
• action_add_packaging_text
• action_add_stores
• action_labels
• action_countries
• action_packager_codes_image

Code pointers

• A followup to the initial implementation: feat: #1136 - handle "action" elements in KP #2440

After a longer investigation, the crash is unrelated, but the new buttons do not seem supported out of the box

Some of the future provisions don't have very good names for the moment. We will ensure consistency when we actually implement them server side

@teolemon I'm implementing 'action_add_origins', 'action_add_packaging_image' and 'action_add_ingredients_image'.
Are you sure about the 'action_' prefix? For the moment we support 'add_categories', 'add_ingredients_text' and 'add_nutrition_facts', and none of them has that prefix, and neither does some of the server code you're referring to.

• It's based on this, but it seems more hardcoded than intended https://github.com/openfoodfacts/openfoodfacts-dart/pull/496/files

this one is for category addition

@M123-dev @monsieurtanuki The screenshots above show the current behaviour. Are we sending the proper thing from the server (it seems so from the example below) ?

I would expect the app to behave like for add categories
