Build core domain: orgs, users, jobs, locate points, auth, live map

Replaces the device-events demo with the actual product:

- Prisma + PostGIS data layer (postgis/postgis:17-3.5). Lat/lng decimals
  are the source of truth; a generated geometry(Point,4326) column with
  a GIST index backs bbox queries. Migrations apply on container boot.
- JWT auth (bcryptjs + httpOnly cookie) with public registration that
  creates an org; per-org roles (ORG_ADMIN/MEMBER/VIEWER) enforced by
  guards on all /orgs/:orgId routes.
- Scoped API keys (X-API-Key, sha256-hashed, shown once) for
  programmatic access, manageable by org admins.
- REST API: jobs/tickets CRUD with filters, points query (time range,
  recordedAt cursor, bbox), members, devices, api-keys.
- MQTT ingest: devices publish to devices/{username}/points and /jobs;
  unknown tickets auto-create stub jobs (source=DEVICE); every message
  is raw-logged to device_events; acks on devices/{username}/jobs/ack.
  Broker gets a dedicated backend user; testuser is now a plain device.
- Realtime: plain-WS gateway at /api/ws (socket.io removed) with
  cookie auth and per-job channels feeding the map live.
- Next.js frontend: login/register, jobs list with filters, job detail
  with live Google map (APWA utility colors, polylines per run) behind
  a provider-neutral JobMap abstraction for a future Esri swap, and
  settings pages for members/devices/api-keys.
- Seed: Umagul org, admin user, testuser device, demo job with RTK
  points. Sample publisher updated to the new topic contract.
