ci(mobile-e2e): expose mavenLocal globally for the consumer Gradle build

The Publish step puts the clerk-android snapshot in ~/.m2/repository, but
the quickstart's android build can't see it: `expo prebuild --clean`
regenerates android/build.gradle from template without mavenLocal(), and
adding mavenLocal to packages/expo/android/build.gradle only configures
the library's own repository chain — not the consumer's.

Drop a global init script in ~/.gradle/init.d/ so every Gradle invocation
on the runner (prebuild plugin resolution + :app:assembleRelease) picks
up mavenLocal. Scoped behind the same snapshot-mode condition so manual
version-string dispatches and PR runs are unaffected.
