feat: add profile edit

Profile page at /profile with first name, last name, display name, telephone and mobile read from AD and shown with the username and e-mail. Only changed fields are written through the directory adapter in one transaction with the audit entry (field names only); numbers are accepted in any common notation and stored as +country code and digits; names are required. Plain-language errors per field, German text and tests; review findings logged in the plan.
