Create Component Test for Grid Teleportation Artifacts

[tobiu]

Create a Playwright Component Test (test/playwright/component/grid/Teleportation.spec.mjs) that reproduces the visual corruption in Neo.grid.Container when using Neo.grid.column.Component.

Requirements:

• Instantiate a Grid with a Store and a Component Column.
• Programmatically scroll the grid to trigger row recycling.
• Assert that cell contents are correct and do not contain duplicate text nodes (e.g., "Stephanie ++Stephanie ++").
• Verify that the loading mask works correctly during rapid scrolling.
