CI: cache the JDK, the SDK and Gradle on the runner host
Every push re-installed a JDK, re-downloaded the Android SDK and let Gradle
fetch its distribution and every dependency again — roughly two of the three
minutes a run took, spent on bytes that never change.

The job now mounts a directory from the runner host at /cache and keeps the
JDK, the SDK and GRADLE_USER_HOME there; both setup steps are skipped when
what they install is already present. Tests and the APK build share one
Gradle invocation instead of paying twice for JVM startup and configuration.

Needs the mount whitelisted in the runner's valid_volumes
(/etc/komodo/stacks/gitea/runner-cache/** on diana).
