refactor: Simplify customer form validation and remove unused fields

- Updated the customer form validation to only check for the business number, removing checks for contact phone and email.
- Removed unused input fields for contact person, phone, and email from the customer management page to streamline the form and improve user experience.
- This change aims to enhance the clarity and usability of the customer management interface across multiple company implementations.
