fix(discount): correct edit-form data + calendar clipping + input styling

- List endpoint returned camelCase keys (getArrayResult) so the edit modal
  read empty discount_type/target_*; return toArray() (snake_case) instead.
- Portal the Persian date-picker calendar to body (fixed) so it no longer
  renders under the modal's overflow-scroll body.
- Style the PriceInput/number fields with cp-input in the rule modal.
