Minor - V0.3.0 - Ajoute frein classique et frein à main - V

Adds a traditional brake alongside the existing handbrake functionality.

This change allows for more controlled deceleration using a standard braking system and introduces a brake power parameter in the vehicle controller for further adjustment. The input manager is updated to accommodate a new brake input, and the vehicle controller uses this input to apply a progressive braking force, particularly at lower speeds.

Also corrects a typo in the braking logic.
