The reporting schema (fn_live_positions/fn_vehicle_track/fn_trips_for_map,
the v_trips materialized view + indexes, filter/summary views, refresh_log)
backs the dashboard_api map endpoints but existed only on the prod DB, in no
migration — a rebuild would have lost it. Captured the live DDL into
migrations/11_reporting_schema.sql (idempotent: IF NOT EXISTS / CREATE OR
REPLACE, search_path set for unqualified base-table refs, guarded grants) and
registered it in run_migrations.py. Verified it applies cleanly against prod
inside a rolled-back transaction.
