feat: Hunger games: a better loading view + we finally support errors…

[g123k]

Hi everyone,

I've reworked a bit the Hunger game page, with:

• A loading view with some Text instead of a vague Progress Bar
• We now catch errors 💥
• … and we can even retry the request 👍
• There are some minor tweaks for the question page and the congrats Widget
• With the need to retry requests, there's no more a FutureBuilder, hence needing a bit more code
• Some Dart 3 code (sealed classes, enhanced switch)

Some screenshots:

I wonder why we try to make Hunger Games an overlay vs a dedicated screen. (I do understand it when the widget is shown on a product)

Suggested change

	"hunger_games_loading_line1": "Please let us a few seconds…",
	"hunger_games_loading_line1": "Just a few seconds…",

Do we want a We/You wording?

As it's a game, that why I've switched to a more familiar language, but feel free to revert this change

You're totally right and would be interesting to also use the onboarding from the website, to clarify that's another feature from the main app. I note this for next "sprint".
