feat(lora-randomizer): prevent early watch triggers by tracking mount state

Add isMounted ref to LoraRandomizerWidget to avoid premature updates from the loras widget watch. The watch now only responds after the component is fully mounted, and the onMounted hook captures the initial loras widget value before enabling the watcher. This prevents the watch from overwriting valid initial data with empty values during component initialization.
