Add comments, fix code on HasIterator and TypeClassification

[adamusgr]

1.Added comments for each method, making the code more understandable and maintainable.

2.Corrected return types and method parameters, adding more checks and accuracy in data type handling.

3.Ensured that the toEnum() method properly checks the values to return the correct classification types (IncomeClassificationType or ExpenseClassificationType).

I cant understand what is wrong with the
$this->assertTrue($classifications->get(IncomeClassificationCategory::CATEGORY_1_95)->contains(null));

[firebed]

null is a valid classification type for classification category categor1_95. In your PR you replaced

return empty($this->toArray()) || in_array($value, $this->toArray(), true);

with this

return empty($this->classifications);

This bypasses the check for null classification type. Also, I don't understand the reason behind completely ditching the TypeClassificationCollection::toArray() method. I believe I used the toArray() method internelly in the class for cosistency.

[adamusgr]

Oh yes!! Sorry, but I didn’t quite understand the class correctly. Your code is soooo large, and honestly, you've done a really great job.

I restored the functions to their original state. I left the comments.

Frankly, I wouldn't touch a code if I don't fully understand it 😃

On a second thought, it looks better accessing the classifications property directly via $this->classifications within the class itself, so what you did was indeed on point. If ever we need to add a specific logic (like formatting or filtering), it makes more sense to put this logic inside the toArray() method without worrying if we break the internal use case.

I know that you reverted the change, but is this something you would like to re-implement?
I noticed some PSR-12 issues. Before merging pleaase see that there are no extra spaces and indentation is correct (lines 43 and 176).

For now, I'll leave it as it is until I fully understand your logic. If you still think we should make the change, that's okay.

[firebed]

I could proceed to make the changes, if you'd prefer.

Yes go on!!!
