Refactors modifier system to use StatsComponent

Moves modifier logic to utilize a central StatsComponent for managing and applying stat modifications.

This change centralizes stat management and simplifies the application of modifiers, enhancing code maintainability and reducing redundancy.
It also moves modifier files to the correct directory.
