Add Impressum and QR code management templates
- Created a new Impressum page with legal information and contact details. - Developed admin link page for linking QR codes to events with form functionality. - Implemented QR code dashboard for managing QR code sets, including creation and quick actions. - Added detailed view for QR code sets, allowing addition of QR codes and management actions. - Introduced static file serving for favicon and related images. - Established views for static content pages (about, contact, privacy, terms). - Implemented translation management scripts for compiling and updating translations.
