Refactor file loading and code retrieval logic

This commit refactors the code in the `Page` component to improve the file loading and code retrieval logic. It removes the hardcoded initial code value and replaces it with an empty string. It also updates the `useEffect` hook to properly handle the startup of the application and retrieve the code content using the `Pterodactyl` API. Additionally, it updates the rendering of the breadcrumbs and adds a save button to the file editor.

Refactor file directory change functionality

This commit refactors the `changeDirectory` function in the `Index` component of the `FilesEditor` module. The function is removed as it is no longer used and has been replaced with a more efficient approach to handle directory changes.
