John Cardinal bd4494abac case 4712 - customer contacts reach only their own customer's work orders ...

Step 2 of 4712 (security review F13). The customer work-order rights checked
only tag-based feature switches, never which customer a work order belongs to.
New UserBiz.CustomerContactOwnsCustomerAsync (own customer, or for a head
office contact a customer of its head office), used by:
- workorder/customer/{id}: another customer's work order is not found (404);
- customer work order report (-100): exactly one work order, which must be the
  contact's (the renderer used every id it was given);
- work order attachment list and download for contacts; other attachment types
  are refused to contacts (the customer screens show them only on work orders).

Checked: other customer's work order 404 (was 200); report on another's or on
two work orders not found; own customer report still accepted (202).
