fix(customers): improve type safety in assign to company modal

- Add ChangeEvent import for proper TypeScript typing
- Remove unused register function from useForm hook
- Refactor onChange handler with explicit ChangeEvent<HTMLSelectElement> type annotation
- Extract target value into variable for improved readability
- Ensure consistent form field updates between setValue and setCompanies calls
- Improve type safety and reduce potential runtime errors in form handling
