Pull request overview

Updates the PivotGrid fieldChooser nested option typings to accept CSS-like string sizes (in addition to numbers) across the core TypeScript declarations and framework wrappers, keeping the public API surface consistent for PivotGrid consumers.

Changes:

• Broadened dxPivotGridOptions.fieldChooser.height/width types from number to number | string in the public .d.ts sources and the aggregated dx.all.d.ts.
• Updated Vue, React, and Angular wrapper typings/prop declarations to match the new number | string contract.
