feat: enhance checkRows function to support row configuration for dynamic table rendering

[npapp-dev002]

The previous version called cy.get('cx-table th').then(...) inside the rows.forEach loop — once per row. Cypress .then() callbacks are queued asynchronously. By the time the first callback executes, the synchronous forEach has already finished and rowIndex has reached its final value (e.g. 3 for all rows), so every assertion used the wrong row index.
The fix: cy.get('cx-table th').then(...) is called once, outside the rows loop. Inside the single .then() callback:

1. The domIndexByLabel map is built synchronously from the real <th> elements.
2. All row/column assertions are issued synchronously within that same callback, so rowIndex increments correctly in step with each row's assertions being queued into Cypress's command queue.
