android(build): inject JitPack repo so LiveKit's audioswitch fork resolves

Codemagic build failed at :app:checkDebugAarMetadata — "Could not find
com.github.davidliu:audioswitch". LiveKit Android 2.29.2 pulls in that
JitPack-only fork (commit-hash version), and Gradle resolves the whole
:app transitive graph against the APP module's (+ allprojects) repos, not
the native-call plugin's. The plugin-level jitpack repo was therefore
ignored. android-patch.js now injects `maven { url 'https://jitpack.io' }`
into the generated root build.gradle's allprojects{} (and settings.gradle
dependencyResolutionManagement{} if a newer template uses it). Idempotent,
build-tolerant. TECHSTACK rev 3 note updated.
