feat(android): implement plugin diagnostics and fix Vue 3 compatibility

- Add runPluginDiagnostics and openConsole methods to HomeView.vue
- Convert ActionCard.vue from vue-facing-decorator to Composition API
- Enhance App.vue with improved plugin detection and error handling
- Add simplified DailyNotificationPlugin.java with basic methods
- Fix plugin registration in capacitor.plugins.json
- Remove error dialogs, rely on console logging for diagnostics

The Plugin Diagnostics button now provides detailed platform and plugin status information.
