Migrate tests from Testing Library to vitest browser mode destructuring

[Copilot]

Per comment #3563015047, migrated all component tests to use vitest browser mode's destructuring pattern instead of the global screen object.

Changes

• skeleton-svelte (25 files): Updated imports from vitest-browser-svelte, removed screen usage
• skeleton-react (25 files): Replaced @testing-library/react with vitest-browser-react, removed screen usage
• All tests now destructure query methods directly from render() return value

Example

Before:

import { render, screen } from '@testing-library/react';

it('renders', () => {
  render(<Test />);
  expect(screen.getByTestId('root')).toBeInTheDocument();
});

After:

import { render } from 'vitest-browser-react';

it('renders', () => {
  const { getByTestId } = render(<Test />);
  expect(getByTestId('root')).toBeInTheDocument();
});

Fixes

• Corrected pagination test using wrong test ID (first-trigger → last-trigger)
• Fixed import spacing in tabs, slider, and segmented-control tests
