[robertdalmeida]

Summary [Required]

Fix bug 🐞 Validation issue with the FormCardSecurityItem - it accepts 4 digits even though UI accepts only 3.

Behaviour same as CardComponent - When the user enters the cvv code and reaches the max limit then it automatically resigns responder so the possibility of validation error is avoided.

Whats next?

Fix bug 🐞 Constraints issue with the FormCardSecurityCodeItemView.

Code Review

This pull request enhances the security code input behavior in StoredCardInputViewController by managing focus states and implementing the FormTextItemViewDelegate. Key changes include automatically focusing the input field on load, resigning focus upon reaching the maximum character length, and adding integration tests for these behaviors. Feedback suggests improving encapsulation by avoiding direct access to the internal text field and enhancing the user experience by triggering the primary action when the return key is pressed.
