date utils: getMaxDate / getMinDate return number instead of Date object

[Kundan-CR7]

What happened?

The getMaxDate and getMinDate utilities return a numeric timestamp instead of a Date object.

This leads to runtime errors when using Date methods directly:

const result = date.getMaxDate(d1, d2)

console.log(typeof result) // number
console.log(result instanceof Date) // false

result.getFullYear() // TypeError

What did you expect to happen?

The function should return a Date object, consistent with other date utilities in Quasar.

3. Observe that:
   • The returned value is a number

4. Calling getFullYear() throws a TypeError

Additional context

Root cause:
Math.max() and Math.min() convert Date objects to timestamps and return a number.

Suggested fix:
Wrap the return value in new Date(...) to maintain consistency.
