[WIP]feat(ui): add CategorizedManageColumnsModal with Cypress tests for hardware config table

[YuliaKrimerman]

Description

Replaces the generic ManageColumnsModal from mod-arch-shared with a new CategorizedManageColumnsModal component for the hardware configuration table on the Performance Insights tab. The new modal organizes the 22+ manageable columns into categorized expandable sections (General, TTFT Latency, E2E Latency, ITL Latency, Throughput TPS), making it much easier for users to find and toggle columns.

Changes

New component — CategorizedManageColumnsModal:

• Expandable category sections with drag-drop reordering within each section
• Column search/filter across all categories
• Selected count display and "Restore default columns" button
• Category descriptions via help icon popovers
• Empty state when search yields no results
• Proper data-testid attributes on all interactive elements

How Has This Been Tested?

• Cypress E2E tests: 27 mocked tests covering all modal interactions (manageColumns.cy.ts)

  npm run test:cypress-ci -- --headed --no-exit --spec '**/modelCatalog/manageColumns.cy.ts'
