Add support open trace viewer from plugin allure-pytest (flow version allure-2.35.1)

We need to add support for opening the Playwright trace viewer directly from Allure reports (version 2.35.1, Flow UI). Currently, traces are attached but not automatically viewable within the Allure Flow interface.

https://github.com/allure-framework/allure2/pull/2964/commits

Acceptance Criteria:

Traces (trace.zip) attached to test results should be openable directly in the Allure Flow UI (v2.35.1).

A button or link should appear in the report to launch the trace viewer.

Ensure compatibility with existing Playwright trace files.

Expected Result:
Users can open Playwright trace viewer seamlessly from Allure Flow reports without leaving the report context.
