feat: Product page with the status bar from the POC

[g123k]

Hi everyone!

One more feature from the POC: the status bar containing the compatibility score.

🎥 Here's a demo: https://github.com/user-attachments/assets/572374c0-4524-4cdb-ad01-70d9cbea7fe9

FYI, this implementation is temporary to let us revamp the onboarding (by removing the food prefs). Normally, it requires the Sliver mechanism, hence, the non-blocking AppBar on scroll (you have to test to understand this)

Also, I wonder if we shouldn't change a bit the compatibility colors… otherwise, there is never some red. For instance, does 50% deserve a green?

I was thinking of turning the circular numerical indicator into a "Road to Scores" shortcut when it is the case @g123k Otherwise, LGTM

We can do it now, with this integration. But with the new onboarding, instead we will have a "Personalize your score" (or something like) at the top of the screen.
