Description: <!-- Please remove all comments before submitting to avoid them being included in merge commit message -->
## Why are these changes being made?
The oh-3.47.7-dev base branch carried unreleased upstream main changes into material_ui/cupertino_ui. Per the delivery requirement, both packages must match the officially published releases exactly. Upstream published material_ui 1.9.0 and cupertino_ui 1.1.5 on 2026-10-29, so this PR aligns both packages with the latest releases.

## Changelog
- brought in the two upstream release commits:
  - flutter/packages#13434 "[material_ui] Batch release" by Flutter GitHub Bot (2026-10-29): bump material_ui to 1.9.0, update CHANGELOG, consume pending changelogs
  - flutter/packages#13432 "[cupertino_ui] Batch release" by Flutter GitHub Bot (2026-10-29): bump cupertino_ui to 1.1.5, update CHANGELOG, consume pending changelog
- reverted the unreleased upstream main changes brought in by the base branch sync, which are not part of these releases: #13371, #13374, #13443, #13370, #12690, #13372, #13439

## Test Plan
- git diff of both package trees against the release tags material_ui-v1.9.0 / cupertino_ui-v1.1.5 is empty: published content and repo development files are identical to the official release state (the 30-file diff decomposes exactly into the 2 release commits above plus the reverts of the 7 listed unreleased PRs, with zero residue)
- strict bidirectional diff against the pub.dev archives (sha256-verified downloads): zero content differences and no missing published files
- transitional SDK (oh-3.47.7-dev framework + Dart 3.13.5) analyze: zero errors except the 161 TargetPlatform.ohos exhaustiveness sites (material 129, cupertino 32), which are the OHOS-adaptation surface for the next stage; this PR contains no OHOS adaptation
