Update an installer job. The update applies only description, installerAdminId and pin.

The following request fields are accepted but never saved:

• status, outcomeDetails - use POST /public-api/actions/installer-job/v1.0/{installerJob}/change-status with status and outcomeDetails.
• chargePoints, locationId - use POST /public-api/actions/installer-job/v1.0/{installerJob}/assign-charge-points with chargePointIds, locationId or chargingZoneId. These are the action's own fields; the resource payload cannot be reused as is.
• customFields - use POST /public-api/actions/installer-job/v1.0/{installerJob}/set-custom-fields.
• installationAndMaintenanceCompanyId - send the job's current company or leave the field out. A different value is still validated and can return 422. There is no supported way to change the company: delete the job and create a new one with the new company. The new job gets a new ID, and deleting a job sends no webhook.
