2026-07-10: Migrate to Foundry project, upgrade to gpt-5.4 for evaluation model judge

This release migrates the app's infrastructure from a classic Azure OpenAI (kind: 'OpenAI') Cognitive Services account to a Microsoft Foundry account and project (kind: 'AIServices'), so models are now deployed inside a real Foundry project that you can open in the new Foundry portal. Evaluations were also upgraded to use the gpt-5.4 model. Stay tuned for a future release that upgrades evaluations to use the new Foundry evaluation SDK.

What's Changed

• Upgrade eval model to gpt-5.4 and copy evaltools into evals/ by @pamelafox in #3157
• Migrate to Microsoft Foundry account + project (resolves #3084) by @pamelafox in #3158
