fix: Configure Android build for Java 17 compatibility

- Force Java 17 for all Android subprojects in root build.gradle
- Override Capacitor's Java 21 requirement with Java 17
- Exclude .gz files from Android packaging to avoid duplicate resources
- Fixes build errors with Capacitor 6 and Java 17

Android APK builds now working: build/android/ai-mate-debug.apk (17MB)
