fix: replace fastacp uuid import with stdlib import in tutorial tests

Four tutorial test files imported `uuid` via:
  from agentex.lib.sdk.fastacp.base.base_acp_server import uuid

This triggered the full fastacp import chain at test collection time:
  fastacp → types.fastacp → core.clients.temporal.utils
    → temporalio.contrib.openai_agents → opentelemetry.sdk

The test runner installs agentex-sdk from PyPI (not the built wheel),
so the published version's temporalio lacks the [opentelemetry] extra,
causing ModuleNotFoundError at test collection time.

Fix: use `import uuid` from the standard library directly.
