Adds the read-only /analytics/* surface the FleetOps SPA will consume, plus
the migration that backs the fuel roll-up. All endpoints SELECT the indexed
reporting.* / tracksolid.v_* views and never write, so the forthcoming staging
instance can serve them against the prod DB as grafana_ro.
dashboard_api_rev.py:
- GET /analytics/fleet-summary per-vehicle + per-cost-centre roll-up
- GET /analytics/utilisation per-vehicle utilisation + daily fleet trend
- GET /analytics/driver-behaviour per-driver speeding / harsh index
- GET /analytics/fuel actual vs estimated litres (data-gated flags)
- GET /analytics/filters dropdown options (alias of GET /webhook/fleet-dashboard)
- responses run through jsonable_encoder (Decimal->float, date->ISO)
- VTRIPS_REFRESH_INTERVAL_S<=0 now DISABLES the v_trips refresher, so a
read-only staging instance never attempts REFRESH (prod still owns it).
migrations/17_fleetops_fuel_view.sql:
- reporting.v_fuel_daily encapsulates the v_trips->devices join (so the
read-only role needs SELECT only on the view) and grants it to grafana_ro.
Registered 17 in run_migrations.py. Note: live migration head is 16, not 13
as CLAUDE.md implies. Endpoints are unit-compilable but untested live until
the staging bridge (Phase 1) exists.
