fix(apollo-react): show node label fallback tooltips

[KodudulaAshishUiPath]

Summary

• Wrap node label header and subheader text in independent conditional tooltips.
• Use the visible label/subLabel as fallback tooltip content when no labelTooltip override is provided.
• Preserve tooltip trigger props and refs on the underlying label DOM nodes so hover and smart truncation checks work.
• Extend smart tooltip truncation detection to recognize line-clamped multiline overflow.
• Add a BaseNode Storybook story with deliberately long labels and sublabels for visual verification.
