Fix seed widget displaying actual seed instead of -1

The issue was that serializeValue() was updating the widget's display value to the actual generated seed, causing the UI to show the seed number instead of -1. Now the widget value only updates when the user manually sets a specific seed, keeping -1 visible in the UI for random seeds.
