feat(infra): deploy gpt-5-mini and gpt-image-1 models

Adds two new model deployments to the AI Foundry account: gpt-5-mini (reasoning + image-capable chat) and gpt-image-1 (image generation, required for ImageAgent in Use Case 6 / Ad Copy / Content Gen). New parameters: gpt5MiniModelName/Version/DeploymentType/Capacity and gptImageModelName/Version/DeploymentType/Capacity. Wired into both the existing-Foundry and new-Foundry deployment paths.
