Add customer names on the ledger, staff session login, and exclusive jobs.events.

Account-balance stores display names and looks up by name. Edge writes
names on customer create/edit; staff UIs join from edge when needed.
New verae-staff-session issues a host cookie; department HTML redirects
when STAFF_AUTH=1. JOBS_EVENTS_EXCLUSIVE lets jobs-events own the durable
consumer. Catalog index is cards; disabled fleet machines are grey.
