Regression tests for the dataInsightCustomChart ⇄ lineChart/summaryCard
circular import.
`dataInsightCustomChart.json` previously owned both the `function` /
`kpiDetails` definitions and `oneOf` `$ref`s to `lineChart.json` /
`summaryCard.json`, while those two `$ref`-ed the definitions back.
Generated Pydantic v2 models tripped on the cycle with
``AttributeError: partially initialized module ... has no attribute
'Function'``.
The fix extracted the shared definitions into ``chartFunctions.json`` so
the chart modules depend only on it, never on ``dataInsightCustomChart``.
