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.

Per-package coverage and bundle size on this PR. New-line coverage = of the source lines this PR adds or changes, the % hit by tests.

_{"Coverage" is each package's own coverage.include scope (e.g. apollo-core instruments only scripts/). "Packed"/"Unpacked" come from npm pack --dry-run and only cover built packages — "—" means not measured this run (package not affected / not built). "vs main" is the packed (gzipped) delta against the last successful main build (the package-sizes artifact from the Release workflow); "—" there means no main baseline was available this run. The baseline is main's latest build, not this PR's exact merge-base, so it includes any drift since the branch diverged. Packages with no vitest config are omitted.}

the tooltip overlaps the node itself

[SreedharAvvari]

[medium] The tooltip coverage stops at the mock boundary. These NodeLabel tests replace CanvasTooltip with a test double, so they prove the mock clones trigger props but do not exercise the real integration this PR relies on: CanvasTooltip ref composition, TooltipTrigger asChild, and smart truncation checking the actual label element. That leaves the fallback tooltip behavior unprotected.

[SreedharAvvari]

Suggested change:
Add one integration-style test that uses the real CanvasTooltip path, or a focused CanvasTooltip + NodeLabel harness, and verifies a line-clamped NodeLabel opens only when the actual label element is truncated. Keep this mock for unit-level content assertions if it is still useful.
