[Number question tasks] Add validation & restrictions for allowed number values

[jcqli]

Prevent user from entering numbers larger than precision allowed by firebase

@gino-m @rfontanarosa Do you know what the max is?

@jcqli Something I found about the limit

Integers: Firestore supports int (32-bit signed integers) and long (64-bit signed integers). There’s no enforced precision limit, but the maximum size for integers is constrained by the type:
32-bit integers: Can store values from -2,147,483,648 to 2,147,483,647.
64-bit integers: Can store values from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
