fix: resolve android compilation error for AppHandle method

Fixes a CI build failure on Android targets: `error[E0599]: no method named run_mobile_plugin found for struct AppHandle`.

- Removed the direct `run_mobile_plugin` call on `AppHandle` in `commands.rs`.
- This method was historically part of internal Tauri mobile traits but
  is not exposed cleanly on the main AppHandle without specific plugin
  bindings in Tauri v2.
- Replaced with a log statement for the MVP. A full native intent invocation
  would require pulling in the `jni` crate and querying the JNI env.
