[refactor] remove intermediate Wrapper component

[severo]

Remove Wrapper, by changing DataProvider to a hook (useData), and removing ErrorProvider.

Also:

• fix a possible issue if onError calls useState (we cannot call onError during rendering)
• rename 'key' to 'dataId' for clarity

Pull request overview

This PR refactors the component architecture by converting DataProvider from a React context provider to a custom hook (useData), removing the ErrorProvider and Wrapper components, and inlining the Wrapper logic directly into HighTable. The refactoring improves code organization by making data flow more explicit through props rather than implicit through context.

Changes:

• Converted DataProvider to useData hook that returns dataId, version, and numRows
• Removed ErrorProvider and ErrorContext, passing onError as explicit props to components that need it
• Removed Wrapper component and merged its logic into HighTable component
• Updated all affected providers to receive data, numRows, and onError as props instead of consuming them from context
• Refactored RowsAndColumnsProvider to use useEffect pattern instead of state-based fetch management
• Updated CellNavigationProvider to accept numRows and optional dataId props
• Migrated tests from DataProvider.test.tsx to useData.test.ts with appropriate adjustments

src/hooks/useData.ts:8

• The JSDoc comment mentions "through the DataContext" but DataContext has been removed in this refactoring. The comment should be updated to reflect that this is now a hook that returns data frame state.
