fix(preflight): Correct parameter order and add IP/fingerprint reporting

- Fix update_worker_preflight call to use correct parameter order:
  (worker_id, transport, status, ip, response_ms, error, fingerprint)
- Add proxyIp to both curl and http preflight reports
- Add fingerprint JSONB with timezone, location, and bot detection data
- Log HTTP IP and timezone after preflight completes

-## Worker Architecture (Kubernetes)
-
-### Persistent Workers (StatefulSet)
-
-Workers run as a **StatefulSet** with 8 persistent pods. They maintain identity across restarts.
-
-**Pod Names**: `scraper-worker-0` through `scraper-worker-7`
-
-**Key Properties**:
-- `updateStrategy: OnDelete` - Pods only update when manually deleted (no automatic restarts)
-- `podManagementPolicy: Parallel` - All pods start simultaneously
-- Workers register with their pod name as identity
-
-**K8s Manifest**: `backend/k8s/scraper-worker-statefulset.yaml`
-
-### Worker Lifecycle
-
-1. **Startup**: Worker registers in `worker_registry` table with pod name
-2. **Preflight**: Runs dual-transport preflights (curl + http), reports IPs and fingerprint
-3. **Task Loop**: Polls for tasks, executes them, reports status
-4. **Shutdown**: Graceful 60-second termination period
-
-### NEVER Restart Workers Unnecessarily
-
-**Claude must NOT**:
-- Restart workers unless explicitly requested
-- Use `kubectl rollout restart` on workers
-- Use `kubectl set image` on workers (this triggers restart)
-
-**To update worker code** (only when user authorizes):
-1. Build and push new image with version tag
-2. Update StatefulSet image reference
-3. Manually delete pods one at a time when ready: `kubectl delete pod scraper-worker-0 -n dispensary-scraper`
-
-### Worker Registry API
-
-**Endpoint**: `GET /api/worker-registry/workers`
-
-**Response Fields**:
-| Field | Description |
-|-------|-------------|
-| `pod_name` | Kubernetes pod name |
-| `worker_id` | Internal worker UUID |
-| `status` | active, idle, offline |
-| `curl_ip` | IP from curl preflight |
-| `http_ip` | IP from Puppeteer preflight |
-| `preflight_status` | pending, passed, failed |
-| `preflight_at` | Timestamp of last preflight |
-| `fingerprint_data` | Browser fingerprint JSON |
