Add /otlp/ segment to observability exporter URL paths

[Copilot]

Summary

• Update Agent365Exporter to include /otlp/ in the trace export URL paths (both standard and S2S endpoints)
• Aligns exporter routes with the OTLP endpoint naming convention: .../tenants/{tenantId}/otlp/agents/{agentId}/traces
• Update corresponding test assertions to match the new URL format

Port of microsoft/Agent365-nodejs#229 to Python.

Changes

• utils.py: Updated build_export_url() URL paths from .../tenants/{tenantId}/agents/{agentId}/traces to .../tenants/{tenantId}/otlp/agents/{agentId}/traces (both standard and S2S)
• agent365_exporter.py: Updated docstring to reflect new URL format
• test_agent365_exporter.py: Updated all 11 test assertions to match new URL format

Test plan

• Updated existing exporter unit tests to validate new URL paths (19/19 passing)
• Verify export succeeds against the updated service endpoints

Pull request overview

Updates the Agent365 observability HTTP exporter URL routing to include an /otlp/ path segment, aligning Python’s exporter endpoints with the service’s OTLP-style route naming.

Changes:

• Update build_export_url() to emit .../tenants/{tenantId}/otlp/agents/{agentId}/traces (standard + S2S).
• Refresh exporter docstring endpoint examples to reflect the new URL format.
• Update unit test assertions to match the new URL paths.

• build_export_url() concatenates endpoint and endpoint_path directly. If endpoint is configured with a trailing slash (e.g. https://example.com/) or includes a path (allowed today by get_validated_domain_override() for scheme URLs), this will produce URLs like https://example.com//observability/... or https://example.com/foo/observability/..., which can lead to incorrect routing/404s depending on the server. Consider normalizing endpoint (e.g., stripping trailing / and/or rejecting non-empty parsed.path for overrides) or constructing the URL via urllib.parse joins to avoid accidental double slashes/path stacking.

    endpoint_path = (
        f"/observabilityService/tenants/{tenant_id}/otlp/agents/{agent_id}/traces"
        if use_s2s_endpoint
        else f"/observability/tenants/{tenant_id}/otlp/agents/{agent_id}/traces"
    )

    parsed = urlparse(endpoint)
    if parsed.scheme and "://" in endpoint:
        return f"{endpoint}{endpoint_path}?api-version=1"
    return f"https://{endpoint}{endpoint_path}?api-version=1"
