✨ Add Smooth Transition to Hamburger Icon for Navigation Toggle

[menukfernando]

Description

📌 Currently, when the hamburger icon is clicked to show or hide the navigation menu, there is no smooth transition effect applied. The change between states feels abrupt and could be improved for a better user experience.

This issue proposes adding a simple transition effect to the hamburger icon to ensure a smoother and more visually appealing interaction when toggling the navigation menu.
