Update SelectPanel test from Jest to Vitest

[Copilot]

This PR migrates the SelectPanel test file from Jest to Vitest as part of the broader test suite migration effort.

Changes Made

Configuration Updates:

• Added <rootDir>/src/SelectPanel/ to the Jest modulePathIgnorePatterns in jest.config.js to exclude it from Jest runs
• Added SelectPanel test pattern to the Vitest browser configuration to include it in Vitest runs

Test File Migration:

• Updated imports to use Vitest (describe, expect, it, vi, beforeEach) instead of Jest
• Replaced all Jest mocking functions:
  • jest.fn() → vi.fn()
  • jest.useFakeTimers() → vi.useFakeTimers()
  • jest.runAllTimers() → vi.runAllTimers()
  • jest.useRealTimers() → vi.useRealTimers()
  • jest.advanceTimersByTime → vi.advanceTimersByTime
• Replaced global.Element.prototype.scrollTo = jest.fn() with globalThis.Element.prototype.scrollTo = vi.fn() for browser compatibility
• Removed setupMatchMedia() usage and import as specified in migration guidelines
• Restored original import from ../utils/testing for the getLiveRegion utility

Testing

The SelectPanel test file has been successfully migrated to Vitest and added to the browser test configuration. The tests will now run as part of the Vitest component test suite using the browser environment.

Fixes #6381.
