ci: add missing androidx.test:runner dep for AndroidJUnitRunner

Previous CI run got all the way through SDK install, KVM, emulator
boot, APK install, and instrumentation start before failing with:

    java.lang.RuntimeException: Unable to instantiate instrumentation
    androidx.test.runner.AndroidJUnitRunner:
    java.lang.ClassNotFoundException: Didn't find class
    "androidx.test.runner.AndroidJUnitRunner" on path: DexPathList[...]

In modern androidx.test versions, ext:junit and runner are separate
artifacts. ext:junit ships AndroidJUnit4 + ApplicationProvider; runner
ships the AndroidJUnitRunner class that testInstrumentationRunner
references. Without the runner dep on the androidTest classpath the
class is missing from the test APK and instrumentation start fails
at test-run time — there's no compile-time check because
testInstrumentationRunner is a string property.

Add androidx.test:runner 1.6.2 (matches the other 1.6.x deps) to
the version catalog and to androidTestImplementation. The catalog
comment captures the failure mode so the gotcha is documented for
future-me.
