Adds a fully-provisioned Grafana dashboard for NOC operators to monitor
80 vehicles in real-time: live geomap with direction arrows, speed, driver
info, and color-coded plates. Includes datasource and dashboard provider
YAMLs, dashboard JSON (schemaVersion 39 / Grafana 11.0.0), and
docker-compose updates to mount provisioning at container start.

Port 8000 was already in use on the host. Updated uvicorn to listen
on 8888. Added 6 importable n8n workflow JSON files for Jimi push
data forwarding (OBD, faults, alarms, GPS, heartbeats, trips).

dict.get("result", []) returns None when key exists with null value.
Changed to resp.get("result") or [] which handles both cases.

- Change image from timescaledb-ha:pg16-ts2.15-oss to pg16-ts2.15
(OSS edition lacks compression, retention, continuous aggregates)
- Add postgresql-client to Dockerfile for psql binary
- Rewrite run_migrations.py to use psql instead of psycopg2
(psql runs each statement independently; psycopg2 wraps the
entire file in one transaction so one error rolls back everything)
- Add schema verification: exits 1 if critical tables missing,
preventing services from starting with broken schema

Coolify doesn't support service_completed_successfully dependency.
Each Python service now runs 'python run_migrations.py' before its
main process. SQL is idempotent so concurrent runs are safe.

- New run_migrations.py: executes 02_*.sql and 03_*.sql in order
- New db_migrate service: runs once before all other services start
- All services now depend on db_migrate (service_completed_successfully)
- Tolerates re-deploy: catches errors from already-existing objects

Port 8000 was already allocated on the host. On Coolify, Traefik routes
external traffic to the container internally — no host port needed.
