Adding scrollbar on overflow itens modal (#400)

Description:
This pull request proposes the addition of a scrollbar to the modal
window containing advanced settings when the number of input fields
exceeds the limit of the screen. This enhancement aims to improve user
experience by providing a convenient way to access all settings, even
when the available screen space is limited.
The number of inputs in the screen is limited by a variable on Utils
that can be easily changed in the future if It's needed.
