Upgrade Chapter 1 to .NET 10

[Copilot]

📋 Description

Upgrades Chapter 1 from .NET 9 to .NET 10. Addresses breaking changes in OpenAPI/Swagger stack and Aspire versioning.

Framework & Core Packages

• Target framework: net9.0 → net10.0
• EF Core, ASP.NET Core packages: 9.0.x → 10.0.x
• Aspire packages: 9.0.0 → 13.0.2 (Aspire skipped versions 10-12)

CI/CD Pipeline

• GitHub Actions workflow: Updated to use .NET 10.0.x in both build and test jobs

OpenAPI Stack Breaking Changes

• Namespace migration: Microsoft.OpenApi.Models → Microsoft.OpenApi
• API deprecation: WithOpenApi(Func<OpenApiOperation, OpenApiOperation>) → WithSummary() + WithDescription()
• Swashbuckle: 9.0.4 → 10.0.1 (requires Microsoft.OpenApi >= 2.3.0)

Example endpoint change:

// Before (.NET 9)
.WithOpenApi(operation => new OpenApiOperation(operation)
{
    Summary = "Signs prepared contract",
    Description = "This endpoint is used to sign prepared contract by customer."
})

// After (.NET 10)
.WithSummary("Signs prepared contract")
.WithDescription("This endpoint is used to sign prepared contract by customer.")

Updated the GitHub Actions workflow to use .NET 10.0.x in commit 0659f4b. Both the build and test jobs now use dotnet-version: 10.0.x instead of 9.0.x.
