Update to .NET 10

[Copilot]

Migrates the repository from .NET 9 to .NET 10, updating SDK references, target frameworks, and package versions across all projects and tooling configurations.

Changes

• Project files: Updated TargetFramework from net9.0 to net10.0 in BackEnd and FrontEnd projects
• Package references: Upgraded Microsoft.AspNetCore.OpenApi from 9.0.* to 10.0.* (resolves to 10.0.0)
• DevContainer: Updated base image to mcr.microsoft.com/dotnet/sdk:10.0 and TARGET environment variable
• CI/CD: Updated GitHub Actions workflow to use dotnet-version: '10.0.x'
• IDE configuration: Updated VS Code launch.json debug paths to reference net10.0 output directories
• Documentation: Updated ASP.NET Core documentation link to reference version 10.0

Both projects build successfully and maintain backward compatibility. The Scalar.AspNetCore package (2.0.36) is compatible with .NET 10.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• learn.microsoft.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
