Wire KeepRunningInTray to runtime so tray, close, and autostart follow the saved setting.

Autostart entries pass --start-in-tray only when the tray is enabled; Settings warns that the notification icon needs a restart (Fyne limitation).

+**KeepRunningInTray is wired to runtime; autostart respects the tray setting.**
+
+**Application:**
+
+- **Keep running in the system tray** now controls behaviour: with the tray on
+  (default), closing the window hides it and autostart uses `--start-in-tray`;
+  with the tray off, closing quits the app and autostart opens the main window.
+- Saving a tray change updates close behaviour and the autostart entry
+  immediately. The notification-area icon follows the saved value after a
+  restart; Settings shows a hint when a restart is needed (Fyne cannot add or
+  remove the icon mid-session).
+- A stale autostart shortcut that still passes `--start-in-tray` no longer hides
+  the window when the tray setting is off — saved config wins over the CLI flag.
+
 **The branded theme is the default, Fyne's built-in theme is System, and the
 test suite is leaner.**
