🛡️ Sentinel: [HIGH] Fix Server-Side Request Forgery in IMAP connections

Browse Source 
🚨 Severity: HIGH
💡 Vulnerability: User-provided IMAP `host` in `_test_imap_connection` and `pull_inbox` was not validated against private IPs, creating an SSRF risk.
🎯 Impact: Attackers could abuse the endpoints to port-scan or interact with internal/private network services.
🔧 Fix: Integrated `is_private_ip` from `app.utils.network` to block connections resolving to private, loopback, link-local, or reserved IPs.
✅ Verification: Ran `test_imap_tasks.py` and `test_api_imap_accounts.py` successfully. Checked `ruff` output and diffs. Removed all scratch files from the commit.

### Docker Compose
Scale workers independently:
Use the `deploy.replicas` setting (requires Docker Swarm mode) or simply run multiple workers:
```yaml
worker:
deploy:
replicas: 3
```
Or scale after deployment:
```bash
docker compose up -d --scale worker=3
docker-compose up -d --scale worker=3
```
Each worker processes tasks from the Celery queue independently. Ensure the shared `workdir` volume is accessible from all worker containers.
> **Important:** The `beat` service (Celery Beat scheduler) must always run as exactly **one** instance. It is defined as a dedicated service in `docker-compose.yaml` with a fixed `container_name`. Do not scale it.
### Scaling the API
API pods are fully stateless (sessions use encrypted cookies, not server-side state) and can be scaled behind a load balancer:
```bash
docker compose up -d --scale api=3

### Health Check Endpoint
DocuElevate exposes three health-related endpoints:
| Endpoint | Auth | Purpose |
|----------|------|---------|
| `GET /api/diagnostic/healthz/live` | None | Lightweight liveness probe — returns 200 if the process is running |
| `GET /api/diagnostic/healthz/ready` | None | Readiness probe — checks database and Redis (503 when DB is down) |
| `GET /api/diagnostic/health` | Required | Full status for monitoring dashboards (Grafana, Uptime Kuma) |
For **Kubernetes probes**, use the unauthenticated endpoints:
```yaml
livenessProbe:
httpGet:
path: /api/diagnostic/healthz/live
port: 8000
readinessProbe:
httpGet:
path: /api/diagnostic/healthz/ready
port: 8000
```
For **uptime monitors** (Uptime Kuma, Grafana, etc.), use the authenticated endpoint:
DocuElevate exposes `/api/health` for readiness probing. Configure your uptime monitor to poll this endpoint:
```bash
curl http://docuelevate.example.com/api/diagnostic/health
# Expected: {"status": "healthy", ...}
curl http://docuelevate.example.com/api/health
# Expected: {"status": "ok", ...}
