fix(ci): build open-next in a dedicated step and skip turbo for wrangler

Turbo's persistent-task output buffering swallows wrangler dev's readiness
signal in CI, making Playwright's webServer probe time out at 180s even
though the preview eventually comes up. Move the OpenNext build to a
dedicated CI step so Playwright's webServer can invoke wrangler dev
directly, keeping stdout attached to the CI log and removing the
dependsOn chain indirection.
