Fixed
- On booking pages using the inquiry layout, required contact fields such as billing address, mobile number, company email or VAT ID were neither shown nor submitted, so an inquiry was rejected with "Please fill in all required fields" even though every visible field was filled. These fields now appear, are checked on submit, and are sent correctly.
- The link in notification emails – for example a new inquiry or an assigned task – led nowhere because it was built without a full address. The links are now complete and open the right entry directly.
