Preserve OpenSearch Serverless hook configuration when deferring

[LE0-Lin]

Closes: #72280

This preserves the AWS hook configuration when OpenSearchServerlessCollectionActiveSensor switches to its deferrable trigger.

The change:

• forwards region_name, verify, and botocore_config from the sensor to the trigger;
• carries those values through AwsBaseWaiterTrigger serialization;
• uses them when constructing OpenSearchServerlessHook;
• adds regression coverage for the sensor defer payload, hook construction, and serialization/reconstruction with both collection ID and collection name.

Local validation:

• Ruff formatting and linting pass for all four changed files.
• The trigger constructor/serialization consistency check passes.
• The targeted Breeze tests could not start because Docker Desktop failed to initialize on this Windows host; the same targeted tests are covered by this PR's Linux CI.

Was generative AI tooling used to co-author this PR?

• Yes (OpenAI Codex)

OpenAI Codex was used for limited implementation and testing assistance. All changes were reviewed and validated by me.

Just one minor comment. Looks good otherwise.
