fix(app-admin): call onClose callback when dialog is closed

The useDialogs hook was not triggering the onClose callback when dialogs
were dismissed. The closeDialog function in DialogsContext only removed
the dialog from state without executing the user-provided onClose callback.

This fix retrieves the dialog from state before removal and calls the
onClose callback if it exists, ensuring proper cleanup and event handling
when dialogs are closed through any method (cancel button, accept button,
or programmatic closure).
