ISSUE 1: Add topBar, fightResult and addFight components in index.tsx

[Lenoxo]

On this stage, you only need to focus on creating the components for the index.tsx page and show a very basic layout aligned with the design.

Details come later, as they say in Refactoring UI.

Add these components with dummy data within them for now:

1. topbar
2. fightResult
3. addFight

Later on, you have time to style them.
