Bootstrap KwabaTV Gradle project, minimal WebView shell

Gradle wrapper pinned to 8.7, AGP 8.5.2, compileSdk 34/minSdk 21/
targetSdk 34 - the tested combination from the original app.
MainActivity is a placeholder that just loads BuildConfig.WEBSITE_URL
(the new /tv room-list route); the real key-mapping logic is a
separate follow-up commit.

Note for future builds on this machine: Android Studio's bundled JBR
is JDK 25, which Gradle 8.7 cannot run on at all (crashes at startup
with a bare version-string error). Built and verified with a
separately-installed Temurin JDK 21 instead
(C:\Users\GGB\jdks\jdk-21.0.12.1+1) - set JAVA_HOME to that for any
Gradle command in this repo, not the Android Studio JBR.
