Two halves of the same thing. A client login was already pinned to its own
tenant on most reads, but the roster, the B2C customer list and the dashboard
counters were not — a DailyGrubs login listed the whole network's riders.
The other half was missing entirely: Doormile's own staff had no way to look
at one client's slice. Reports accepted ?tenantid= but applied it only to the
consignment count, and bookings accepted it while milers, customers,
consignments and the dashboard ignored it.
effectiveTenantID(c) now resolves both cases in one place — the caller's own
tenant for a client login, the requested one for Doormile staff, 0 for the
whole network. A client asking for someone else's tenantid is refused rather
than silently handed their own data back under the wrong label.
Applied to: milers, customers, bookings, consignments, dashboard, reports and
the rider summary.
