enh: update helm charts to new llm-d-async config values

[evacchi]

Why is this PR needed?

llm-d-async PRs llm-d/llm-d-async#388 and llm-d/llm-d-async#378 update to a cleaner config format; even though the old format is supported, we can keep the two codebases tightly aligned and avoid deprecation warnings.

What does this PR do?

Updates the Helm charts, scripts and tests to align to the llm-d-async codebase. Since the change is not merged yet, this PR is draft, and we might wait for a formal release before merging.

How was this tested?

• Unit tests added/updated/verified
• Integration/e2e tests added/updated/verified
• Manual testing performed

Pull request overview

Updates the repository’s e2e configs, deployment scripts, and documentation to match the newer llm-d-async configuration schema and naming (e.g., ap.transport / ap.transportConfig and llm-d-async chart/deployment identifiers), keeping batch-gateway aligned with the upstream dispatcher project.

Changes:

• Switched dispatcher Helm values from messageQueueImpl/redis.* to transport/transportConfig across e2e values, examples, docs, and benchmark deployment.
• Updated scripts and e2e logic to look for llm-d-async naming (chart path and deployment/service identifiers).
• Refreshed trace/e2e documentation strings to refer to llm-d-async instead of async-processor.
