fix(security): Add auth middleware to unprotected API endpoints

Security audit identified 8 endpoint groups that were publicly accessible
without authentication. Added authMiddleware and requireRole where appropriate.

Protected endpoints:
- /api/payloads/* - authMiddleware (trusted origins or API token)
- /api/job-queue/* - authMiddleware + requireRole('admin')
- /api/workers/* - authMiddleware
- /api/worker-registry/* - authMiddleware (pods access via trusted IPs)
- /api/k8s/* - authMiddleware + requireRole('admin')
- /api/pipeline/* - authMiddleware + requireRole('admin')
- /api/tasks/* - authMiddleware + requireRole('admin')
- /api/admin/orchestrator/* - authMiddleware + requireRole('admin')

Also:
- Added API_SECURITY.md documentation
- Filter AI settings from /settings page (managed in /ai-settings)

+# API Security Documentation
+
+This document describes the authentication and authorization configuration for all CannaiQ API endpoints.
+
+## Authentication Methods
+
+### 1. Trusted Origins (No Token Required)
+
+Requests from trusted sources are automatically authenticated with `internal` role:
+
+**Trusted IPs:**
+- `127.0.0.1` (localhost IPv4)
+- `::1` (localhost IPv6)
+- `::ffff:127.0.0.1` (IPv4-mapped IPv6)
+
+**Trusted Domains:**
+- `https://cannaiq.co`
+- `https://www.cannaiq.co`
+- `https://findadispo.com`
+- `https://www.findadispo.com`
+- `https://findagram.co`
+- `https://www.findagram.co`
+- `http://localhost:3010`
+- `http://localhost:8080`
+- `http://localhost:5173`
+
+**Trusted Patterns:**
+- `*.cannabrands.app`
+- `*.cannaiq.co`
+
+**Internal Header:**
+- `X-Internal-Request` header matching `INTERNAL_REQUEST_SECRET` env var
+
+### 2. Bearer Token Authentication
+
+External requests must include a valid token:
+
+```
+Authorization: Bearer <token>
+```
+
+**Token Types:**
+- **JWT Token**: User session tokens (7-day expiry)
+- **API Token**: Long-lived tokens for integrations (stored in `api_tokens` table)
+
+## Authorization Levels
+
+### Public (No Auth)
+Routes accessible without authentication:
+- `GET /health` - Health check
+- `GET /api/health/*` - Comprehensive health endpoints
+- `GET /outbound-ip` - Server's outbound IP
+- `GET /api/v1/deals` - Public deals endpoint
+
+### Authenticated (Trusted Origin or Token)
+Routes requiring authentication but no specific role:
+
+| Route | Description |
+|-------|-------------|
+| `/api/payloads/*` | Raw crawl payload access |
+| `/api/workers/*` | Worker monitoring |
+| `/api/worker-registry/*` | Worker registration and heartbeats |
+| `/api/stores/*` | Store CRUD |
+| `/api/products/*` | Product listing |
+| `/api/dispensaries/*` | Dispensary data |
+
+### Admin Only (Requires `admin` or `superadmin` role)
+Routes restricted to administrators:
+
+| Route | Description |
+|-------|-------------|
+| `/api/job-queue/*` | Job queue management |
+| `/api/k8s/*` | Kubernetes control (scaling) |
+| `/api/pipeline/*` | Pipeline stage transitions |
+| `/api/tasks/*` | Task queue management |
+| `/api/admin/orchestrator/*` | Orchestrator dashboard |
+| `/api/admin/trusted-origins/*` | Manage trusted origins |
+| `/api/admin/debug/*` | Debug endpoints |
+
+**Note:** The `internal` role (localhost/trusted origins) bypasses role checks, granting automatic admin access for local development and internal services.
+
+## Endpoint Security Matrix
+
+| Endpoint Group | Auth Required | Role Required | Notes |
+|----------------|---------------|---------------|-------|
+| `/api/payloads/*` | Yes | None | Query API for raw crawl data |
+| `/api/job-queue/*` | Yes | admin | Legacy job queue (deprecated) |
+| `/api/workers/*` | Yes | None | Worker status monitoring |
+| `/api/worker-registry/*` | Yes | None | Workers register via trusted IPs |
+| `/api/k8s/*` | Yes | admin | K8s scaling controls |
+| `/api/pipeline/*` | Yes | admin | Store pipeline transitions |
+| `/api/tasks/*` | Yes | admin | Task queue CRUD |
+| `/api/admin/orchestrator/*` | Yes | admin | Orchestrator metrics/alerts |
+| `/api/admin/trusted-origins/*` | Yes | admin | Auth bypass management |
+| `/api/v1/*` | Varies | Varies | Public API (per-endpoint) |
+| `/api/consumer/*` | Varies | Varies | Consumer features |
+
+## Implementation Details
+
+### Middleware Stack
+
+```typescript
+// Authentication middleware - validates token or trusted origin
+import { authMiddleware } from '../auth/middleware';
+
+// Role requirement middleware - checks user role
+import { requireRole } from '../auth/middleware';
+
+// Usage in route files:
+router.use(authMiddleware);                           // All routes need auth
+router.use(requireRole('admin', 'superadmin'));       // Admin-only routes
+```
+
+### Auth Middleware Flow
+
+```
+Request → Check Bearer Token
+         ├─ Valid JWT → Set user from token → Continue
+         ├─ Valid API Token → Set user as api_token role → Continue
+         └─ No Token → Check Trusted Origin
+                      ├─ Trusted → Set user as internal role → Continue
+                      └─ Not Trusted → 401 Unauthorized
+```
+
+### Role Check Flow
+
+```
+Request → authMiddleware → requireRole('admin')
+                          ├─ role === 'internal' → Continue (bypass)
+                          ├─ role in ['admin', 'superadmin'] → Continue
+                          └─ else → 403 Forbidden
+```
+
+## Worker Pod Authentication
+
+Worker pods (in Kubernetes) authenticate via:
+
+1. **Internal IP**: Pods communicate via cluster IPs, which are trusted
+2. **Internal Header**: Optional `X-Internal-Request` header for explicit trust
+
+Endpoints used by workers:
+- `POST /api/worker-registry/register` - Report for duty
+- `POST /api/worker-registry/heartbeat` - Stay alive
+- `POST /api/worker-registry/deregister` - Graceful shutdown
+- `POST /api/worker-registry/task-completed` - Report task completion
+
+## API Token Management
+
+API tokens are managed via:
+- `GET /api/api-tokens` - List tokens
+- `POST /api/api-tokens` - Create token
+- `DELETE /api/api-tokens/:id` - Revoke token
+
+Token properties:
+- `token`: The bearer token value
+- `name`: Human-readable identifier
+- `rate_limit`: Requests per minute
+- `expires_at`: Optional expiration
+- `active`: Enable/disable toggle
+- `allowed_endpoints`: Optional endpoint restrictions
+
+## Security Best Practices
+
+1. **Never expose tokens in URLs** - Use Authorization header
+2. **Use HTTPS in production** - All traffic encrypted
+3. **Rotate API tokens periodically** - Set expiration dates
+4. **Monitor rate limits** - Prevent abuse
+5. **Audit access logs** - Track API usage via `api_usage_logs` table
