feat: Improve the Nutrition Facts screen

[g123k]

Hi everyone,

The nutrition facts screen (the read-only one, in the Product page) has two majors issues:

• A CupertinoPicker is pretty counterintuitive on Android to change the quantity => A simple TextField is used instead
• The screen was poorly accessible (each item on the table was selectable, instead of the whole)

As a always a video, of the feature: Nutrition.webm

Could it possibly be a bottom sheet, with a Copy button

Could it possibly be a bottom sheet, with a Copy button

You mean the sheet or the input text?

[teolemon]

Sheet, possibly?

[g123k]

Sheet, possibly?

Possible.
But it would be nice to validate #4307 first, as there will be new APIs that would be welcomed here
