Ensure Honor and Huawei Maven repos are added to both buildscript.repositories
and allprojects.repositories in root build.gradle. Runtime dependencies like
com.hihonor.mcs:push and com.huawei.hms:push are resolved via allprojects,
not buildscript. Also consolidate all build.gradle modifications to use
withDangerousMod directly, avoiding silent hook drops in Expo SDK 56+.
- Add withOppoPush.js and withVivoPush.js config plugins
- Register new plugins in app.json
- Bump JPush version from 5.8.0 to 6.1.0 in Honor/Huawei/Xiaomi plugins
