Fix: Make image_data a visible widget and remove alert messages

Changes:
- Moved image_data from optional to required (no forceInput)
- image_data is now a multiline STRING widget (auto-filled by file picker)
- Removed alert() and console.log() messages
- Store base64 data in both node.properties and widget.value

This fixes the 'object supporting the buffer API required' error
by ensuring image_data widget exists and can be set by JavaScript.
