Fix trial license key to expire instead of being permanent

The trial license key was incorrectly placed with permanent licenses (gpl-v3, internal-use-in-handsontable), causing it to never expire. Moved it to a separate branch with expiration logic that checks against a hardcoded trial expiry date (May 19, 2026), ensuring it behaves as a time-limited trial license.
