Description

Cypress CI can now wait for the frontend server to start on GitHub runner 2.338.0. That runner upgrades the action's Node runtime from 24.19.0 to 24.21.0, exposing a bug in the HTTP client bundled with Cypress action v7.3.0. The readiness check fails immediately with Socket closed before the connection was established, before tests run.

Update all three action references to SHA-pinned v7.4.4, which includes the upstream fix. Apply the same CI fix as #4387 to release/v4.35, where it blocks #4385.
