Add cron job functionality and Docker integration

- Add is_hidden field to hide components from configurator
- Add colored dot indicator showing component usage status:
  - Green: available in configurator
  - Cyan: used as source for meta-articles
  - Gray: hidden from configurator
- Optimize price recalculation with caching and skip unchanged
- Show current lot name during price recalculation
- Add Dockerfile (Alpine-based multi-stage build)
- Add docker-compose.yml and .dockerignore

+## Cron Jobs
+
+QuoteForge now includes automated cron jobs for maintenance tasks. These can be run using the built-in cron functionality in the Docker container.
+
+### Docker Compose Setup
+
+The Docker setup includes a dedicated cron service that runs the following jobs:
+
+- **Alerts check**: Every hour (0 * * * *)
+- **Price updates**: Daily at 2 AM (0 2 * * *)
+- **Usage counter reset**: Weekly on Sunday at 1 AM (0 1 * * 0)
+- **Popularity score updates**: Daily at 3 AM (0 3 * * *)
+
+### Manual Cron Job Execution
+
+You can also run cron jobs manually using the quoteforge-cron binary:
+
+```bash
+# Check and generate alerts
+go run ./cmd/cron -job=alerts
+
+# Recalculate all prices
+go run ./cmd/cron -job=update-prices
+
+# Reset usage counters
+go run ./cmd/cron -job=reset-counters
+
+# Update popularity scores
+go run ./cmd/cron -job=update-popularity
 ```

-## Development Priorities
-
-1. **Phase 1 (MVP):** Project setup, models, component API, basic UI, CSV export
-2. **Phase 2:** JWT auth with roles, pricing admin UI, all price methods
-3. **Phase 3:** Save/load configs, JSON import/export, XLSX export, cron jobs
-4. **Phase 4:** Usage stats, alerts system, dashboard
-5. **Phase 5:** Polish, tests, Docker, documentation
+- **Alerts check**: Generates alerts for components with high demand and stale prices, trending components without prices, and components with no recent quotes
+- **Price updates**: Recalculates prices for all components using configured methods (median, weighted median, average)
+- **Usage counter reset**: Resets weekly and monthly usage counters for components
+- **Popularity score updates**: Recalculates popularity scores based on supplier quote activity
