chore(litestar): Remove transaction-based tracing

[alexander-alderman-webb]

Description

I've removed

• test_request_body_data_collection()
• test_request_body_data_collection_wins_over_send_default_pii()
• test_cookie_data_collection()

since LiteStar doesn't capture cookies or request bodies on streamed spans.

Issues

Closes #7099

• Please add tests to validate your changes, and lint your code using uv run ruff.
• Add GH Issue ID & Linear ID (if applicable)
• PR title should use conventional commit style (feat:, fix:, ref:, meta:)
