Hubs, Vehicles, App Users, Tripsheets, Exceptions, and Competitive Intel
had full CRUD support in doormileApi.js but no UI anywhere in the console.
B2C Customers had neither. Field bindings for Pricing/Vehicles/Tripsheets/
Exceptions/Customers are confirmed against live read-only API responses;
App Users' write body and both Competitive Intel resources (no documented
schema at all for competitor-branches/carrier-pricing) are still best-effort
guesses and unverified against a real write.
Routed under a new "Fleet & Ops" sidebar group except Customers, which sits
at the top level next to Pricing.
