feat: Add Docker containerization for D2WeaponReport

[Snoww3d]

Summary

• Add multi-stage Dockerfile that builds the application with .NET SDK 7.0, downloads the Bungie manifest via InitEnvironment, and creates a lightweight ASP.NET 7.0 runtime image
• Add docker-compose.yml for easy local development (maps port 5050 to container port 80)
• Add .dockerignore to exclude build artifacts and unnecessary files
• Add skipLibCheck: true to tsconfig.json for TypeScript build compatibility

Test plan

• Run docker build -t d2weaponreport . to build the image
• Run docker run -p 5050:80 d2weaponreport to start the container
• Verify homepage loads at http://localhost:5050/
• Verify weapon analysis works at http://localhost:5050/Home/Index/821154603
• Alternatively, use docker-compose up to build and run
