## Summary by CodeRabbit

* **Chores**
* Improved mobile CI workflow with change-aware Android/iOS build jobs
and updated completion dependencies so tests wait for the relevant
mobile builds.
* **Performance / App Behavior**
* Enhanced Android WebView behavior: improved viewport/WebView tuning,
disabled zoom and scrollbars, and made mixed-content allowance
environment-aware (debug vs non-debug).
* Adjusted Android cleartext traffic handling based on build/debug
settings and Capacitor server URL configuration.
* **Tests**
* Strengthened Electron BYOK storage tests with per-test temporary
directories, mock control, and added coverage for when secure storage is
unavailable.
