Migrate all Apps to Use GitHub Actions for CI/CD

[isaacrlevin]

All Tailwind Traders Apps should use GitHub Actions for CI/CD

• Backend (AKS)
• Website (ASP.NET & React)
• Desktop (WinForms & WPF -.NET Core)
• Rewards (ASP.NET Framework)
• Mobile (Xamarin Forms 4.0)
• Shipping Management (Power App + Azure Serverless)

These Actions should include

• A nightly one to ensure latest in main works
• One for merges into main
• One for PRs
• One for CodeQL Code Scanning (I added it but not sure if some are working)
