Add project AI Gateway enablement sample under 01-connections

[pradeepkintali]

Summary

Adds a new self-contained sample under infrastructure/infrastructure-setup-bicep/01-connections/project-ai-gateway/ that creates a new Azure AI Foundry project under an existing, already AI-Gateway-enabled account and enables the AI Gateway on the project by default.

Unlike the other 01-connections samples (which create a Microsoft.CognitiveServices/accounts/connections resource), this sample provisions the per-project API Management artifacts that mark a project as gateway-enabled.

What it deploys

1. Project under the existing account.
2. APIM Product (subscriptionRequired: true, state: 'published').
3. Product ↔ API association to the gateway's shared API (named after the account).
4. Active APIM Subscription scoped to the product.
5. ARM resource link (Microsoft.Resources/links) from the project to the product — its presence marks the project Enabled on the gateway.

Notes

• Does not modify any existing connection samples.
• main.bicep compiles cleanly (only the expected BCP081 info warning for Microsoft.Resources/links, which does not block deployment).
• Includes README.md, main.bicep, compiled main.json, main.parameters.json, and modules/apim-gateway-artifacts.bicep.
