Normalize license plate input value handling in LicensePlateInput.vue:

- Ensured input field values are updated consistently with `props.actualValue`.
- Replaced raw `newValue` usage with normalized string values for better data integrity.
- Improved checks for synchronization and validation logic (`checkLicensePlateValid`, `searchCustomerRegistrationNumbers`).
