feat: Add CutList.Web Blazor Server application

Add a new web-based frontend for cut list optimization using:
- Blazor Server with .NET 8
- Entity Framework Core with MSSQL LocalDB
- Full CRUD for Materials, Suppliers, Projects, and Cutting Tools
- Supplier stock length management for quick project setup
- Integration with CutList.Core for bin packing optimization
- Print-friendly HTML reports with efficiency statistics
