Pull request overview

This PR addresses an issue where event configuration labels were getting cut off when they exceeded normal length. The fix removes the white-space: nowrap CSS property from table cells, allowing text to wrap naturally instead of being truncated.

Key changes:

• Removed CSS constraint that prevented text wrapping in event configuration table
• Refactored multiple test cases to use proper Pinia store isolation
• Updated DOMParser mocking strategy in XML validator tests to use class syntax with vi.stubGlobal
