feat(isFiniteNumber): add isFiniteNumber

[HoberMin]

Add isFiniteNumber utility function

Summary

Added a new utility function isFiniteNumber that checks if a given value is a finite number. This function also acts as a TypeScript type predicate, helping with type narrowing in TypeScript code.

Implementation Details

• Function takes any value (unknown type) as input
• Returns boolean indicating if the value is a finite number
• Implements type predicate functionality (value is number)
• Uses native typeof and isFinite checks

Usage Examples

import { isFiniteNumber } from '@utils/number';

// Regular numbers
isFiniteNumber(42)        // true
isFiniteNumber(-123.45)   // true

// Special number values
isFiniteNumber(Infinity)  // false
isFiniteNumber(-Infinity) // false
isFiniteNumber(NaN)      // false

// Non-number values
isFiniteNumber('123')     // false
isFiniteNumber(null)      // false
isFiniteNumber(undefined) // false
