Fix: Use correct EUPL 1.2 license instead of MIT

The project uses EUPL v1.2, not MIT. Updated consent dialog to display
the actual EUPL license text and point to the official EUPL license page.

- Changed 'Licentie (MIT)' to 'Licentie (EUPL 1.2)'
- Updated _getLicenseText() with EUPL v1.2 summary
- Fixed license link to https://joinup.ec.europa.eu/collection/eupl/eupl-text-eupl-12
