#2 Load models from obj files

#2 Load .obj mesh

Contents

This PR is trying to resolve:
The engine needs the ability to load both primitive types and custom models. Custom models are a key factor in any rendering engine.

We resolve it by:
Tried to use a custom implementation which for a reason or another does not work. To use an intermediate solution that works, marked a Model_Old class as obsolete and used it to load models.

The approach in this PR has an issue where the textures are not being loaded correctly. This will be fixed in an upcoming PR to keep the changes small enough.

Pull Request Overview

This PR revisits the model loading approach to support custom .obj mesh files by switching from using the Material‐ and Mesh‑based assignment to a Model property, and it updates logging calls to use Debug.Log instead of Console.WriteLine.

• Changed property assignment in BlockBase to use Model instead of separately assigning Material and Meshes.
• Updated logging calls across Editor files with Debug.Log methods and added structured logging parameters.
• Removed several core files (e.g. Texture, Shader, MeshService, etc.) as part of refactoring to transition to a new model loading approach.
