Events menu frontend

1. PDF Handling for Menus

• The backend now supports opening a static mock PDF for menus. Currently, it serves just one placeholder file, but in the future, bar managers will be able to upload their own menu PDFs through the Bar Manager View. These files would be stored in Cloudinary, with their URLs saved in the database and linked to the respective bars.
• In the Frontend you'd need to change the pdfUrl to your IP, as it uses the android setting at the moment.

2. Events Styling & Mock Data Events and Event mock data has been added. Users can now open detailed event views and add events to their calendars. On Android, adding an event requires logging into a Google account, while on iOS, it should work directly with the default calendar. Event cards also display a badge showing how many days are left until the event starts.

3. Share to Instagram Modal Styling The Share to Instagram modal has been styled to ensure a consistent UI.
