[WebPubSub] Fix live tests with AAD-based test resources

[MoChilia]

Description

• Update Web PubSub live test setup to use SDK-created test resources and AAD authentication instead of preconfigured connection-string secrets.
• Add bounded waits/retries around timing-sensitive Web PubSub client reconnect, recovery, group rejoin, and callback scenarios.
• Ignore integration_sample.py in sample validation because it requires multi-client live WebSocket behavior.

All SDK Contribution checklist:

• The pull request does not introduce [breaking changes]
• CHANGELOG is updated for new features, bug fixes or other significant changes.
• I have read the contribution guidelines.

General Guidelines and Best Practices

• Title of the pull request is clear and informative.
• There are a small number of commits, each of which have an informative message. This means that previously merged commits do not appear in the history of the PR. For more information on cleaning up the commits in your PR, see this page.

Testing Guidelines

• Pull request includes test coverage for the included changes.

Pull request overview

Updates the Web PubSub Python SDK live-test and sample setup to rely on test-resources provisioning and AAD auth (instead of connection-string secrets), while improving resiliency of timing-sensitive WebPubSub client tests and excluding a multi-client integration sample from automated sample validation.

Changes:

• Introduce test-resources.bicep and adjust pipeline/test preparers to use endpoint-based configuration and AAD credentials.
• Add bounded waits/retries/timeouts across several live tests to reduce flakiness (reconnect/recovery/group rejoin/list connections/etc.).
• Exclude integration_sample.py from sample validation runs.

• AsyncDefaultAzureCredential and the async service client are created but never closed. This can leak network resources and emit warnings in sample runs; prefer using async with (or explicitly closing) for both the credential and the async client.

async def client_access_url_provider_async():
    credential = AsyncDefaultAzureCredential()
    service_client_async = WebPubSubServiceClientAsync(
        endpoint=os.getenv("WEBPUBSUB_ENDPOINT", ""), hub="hub", credential=credential

Hi @ChenxiJiang333, @mccoyp, @msyyc, @scbedd, could you please review this pr? Your code owner review is required. Thank you!

[msyyc]

Is this sensitive info of azure resources?

[MoChilia]

No, this is non-sensitive.
