refactor(push): unify file modification approach and improve dependency resolution

Simplify Honor push plugin to use withDangerousMod consistently for all file
modifications, replacing the withSettingsGradle approach that silently drops
writes in Expo SDK 56+ multi-vendor plugin scenarios.

Enhance Huawei push plugin to create missing dependencyResolutionManagement
block instead of only appending to existing ones, ensuring CI build paths work
reliably when Gradle's dependencyResolutionManagement takes precedence.

Remove inline settings.gradle/build.gradle generation from CI workflow,
relying on expo prebuild for Gradle file generation.
