ci: run check + APK build natively on the MacBook runner

The desktop runner is gone. Jobs now target label "macbook": a
gitea-runner in host mode on the MacBook Air using Homebrew JDK 21,
the local Android SDK and node 22, so no container or SDK download.
eas.json bumped to 1.22 to match the locally built release.
