PWA status bar hairline sampler (arm64 APK)

#421933373 perf regression check #512898018 Status: New Priority: P3 Build base: 2c508d514e53 + local landscape mitigation

Issue summary

Issue 421933373 reports a thin line under the status bar in installed PWA/TWA flows when resuming app state.

This arm64 build includes the follow-up fix that keeps the top toolbar hairline hidden across PWA orientation changes and resize-driven scene layer updates.

It also includes a local mitigation for the rendering.mobile regression: regular scroll offset updates skip the steady hidden offset, while resize/orientation updates still hide the hairline at the boundary.
