feat(quick-16): convert LLM node to full-bleed, add max tokens, add panel shadow

- LLMGenerateNode: Remove inline provider/model/parameter controls
- LLMGenerateNode: Convert to full-bleed layout with fullBleed prop
- LLMGenerateNode: Show only text output area in node body
- LLMGenerateNode: Keep floating action buttons (copy, regenerate, clear)
- ControlPanel: Add Max Tokens slider to LLMControls (256-16384 range)
- ControlPanel: Add shadow/gradient overlay on left edge of panel
- WorkflowCanvas: Fix type errors with node.data union types (Rule 1 bug fix)
