fix(test-app): add missing plugin imports for proper registration

- Import @capacitor/core for Capacitor platform detection
- Import @timesafari/daily-notification-plugin for plugin availability
- Resolves "Plugin: Not Available" issue in test app

Plugin now properly registers and becomes available at runtime.
