fix(e2e): Restore Settings.app warm-up for sample-application workflow

The sample-application workflow uses its own test runner (maestro.ts)
and doesn't go through cli.mjs, so it doesn't benefit from the Maestro
warm-up flow. Restore the Settings.app warm-up step with the proper
platform-check skip guard to keep it resilient against Tart VM timing.
