Fix: Observability API signature update and Azure AI Foundry endpoint compatibility

[Yogeshp-MSFT]

Summary

Two fixes in src/client.ts to address a TypeScript compilation error and a runtime 400 error when using Azure AI Foundry endpoints.

---

Change 1 — InferenceScope API signature update

The @microsoft/agents-a365-observability package changed the InferenceScope.start() signature in a breaking way.

Before: InferenceScope.start(inferenceDetails, agentDetails, tenantDetails)
After: InferenceScope.start(request, inferenceDetails, agentDetails)

• Line 20 — Replaced TenantDetails import with Request
• Line 207 — Introduced a new Request object to carry conversationId (previously incorrectly placed on AgentDetails)
• Line 215 — Removed conversationId from AgentDetails
• Line 218 — Moved tenantId into AgentDetails.tenantId, removing the separate tenantDetails variable
• Line 223 — Updated InferenceScope.start() call to the new parameter order

Fixes TS errors TS2353 (conversationId not in AgentDetails) and TS2559 (InferenceDetails incompatible with Request).

Change 2 — Azure AI Foundry endpoint support (Lines 59–86)

Azure AI Foundry endpoints (*.services.ai.azure.com/.../openai/v1/...) are OpenAI-compatible and do not accept the ?api-version= query parameter that AzureChatOpenAI unconditionally appends, causing HTTP 400 errors.

• Lines 62–79 — Added a Foundry detection branch: if the endpoint URL contains /v1, use ChatOpenAI with a normalised baseURL (trimmed to .../v1), apiKey set in configuration (required when using a custom baseURL), and an api-key header as required by Azure
• Lines 81–86 — Standard *.openai.azure.com endpoints continue to use AzureChatOpenAI unchanged

Pull request overview

Updates the sample agent to align with a breaking observability API signature change and to support Azure AI Foundry OpenAI-compatible endpoints that reject api-version query parameters.

Changes:

• Updated InferenceScope.start() usage to the new (request, inferenceDetails, agentDetails) signature and moved conversationId into a new Request object.
• Added detection/handling for Azure AI Foundry /v1 endpoints by routing through ChatOpenAI with a normalized baseURL and Azure-required api-key header.
• Ignored generated Agent 365 config files that may contain secrets.
