[Jospin6]

• Styled the sidebar navigation for the dashboard.
• Added icons using font_awesome_rails.
• Implemented sidebar_controller.js to persist the active item state.

Changes:

• Improved sidebar UI/UX.
• Integrated FontAwesome for better iconography.
• Ensured active item state persists across page reloads.

Thank you for the PR @Jospin6 ✨
Currently we are using tailwind for styling so i think it would be better to use https://heroicons.com/ which was made by the same makers

[Jospin6]

Thank you for the feedback! 🙌 That makes sense, I’ll update the PR to use Heroicons for consistency with Tailwind. I’ll push the changes shortly

@Jospin6 After looking at the change you made, I think you might be updating the wrong navigation.
I'll add more details to this issue #86 to better define what you need to work on

[Jospin6]

Great, but I've made changes in the dashboard section of the application; is there any other part I should work on apart from the dashboard? Give me the feedback, and I'll get to work on it right away
