## Summary by CodeRabbit
* **New Features**
* Added a screensaver system with multiple styles (Bouncing Balls, Mystify, Matrix Rain) and a common screensaver interface; auto-starts after inactivity, dismisses on interaction, and supports auto-off/backlight behavior.
* New Display setting and UI dropdown to choose and persist the screensaver.
* **Documentation**
* Added comprehensive screensaver docs covering usage, extension, and configuration.
* **Chores**
* Registered the display-idle service.
* **Bug Fixes**
* Updated LVGL API calls to match renamed functions.
