Add end-to-end startup script and developer onboarding docs

[jongalloway]

Goal

Provide a single script that sets up everything needed to run the full system, plus clear documentation for new developers.

Work needed

Setup script (\scripts/Setup-DevEnvironment.ps1)

1. Check prerequisites (VS 2022, .NET Framework 4.8 SDK, LocalDB, IIS Express)
2. Create LocalDB instances and run schema + seed scripts
3. Restore NuGet packages
4. Build the solution
5. Report ready status with URLs for each web app

Developer docs (\docs/getting-started.md)

• Prerequisites list with download links
• Step-by-step first run instructions
• Architecture overview pointing to each runnable component
• Troubleshooting common issues (port conflicts, LocalDB failures, etc.)

Optional: launch profile

• A solution-level launch configuration that starts all web apps + WCF service together
• Or a \scripts/Start-AllServices.ps1\ that launches everything

Dependencies

• All other runnable-app issues should be complete first

Acceptance criteria

• A fresh clone + running the setup script → working system
• README links to getting-started docs
• No undocumented manual steps required
