Add complete automation, reporting, and CI/CD system

Features Added:
==============

📧 EMAIL REPORTING SYSTEM:
- EmailReporter: Send reports via SMTP (Gmail, SendGrid, custom)
- ReportGenerator: Generate daily/weekly summaries with HTML/text formatting
- Configurable via .env (SMTP_HOST, SMTP_PORT, etc.)
- Scripts: send_daily_report.py, send_weekly_report.py

🤖 AUTOMATED RUNS:
- automated_daily_run.sh: Full daily ETL pipeline + reporting
- automated_weekly_run.sh: Weekly pattern analysis + reports
- setup_cron.sh: Interactive cron job setup (5-minute setup)
- Logs saved to ~/logs/ with automatic cleanup

🔍 HEALTH CHECKS:
- health_check.py: System health monitoring
- Checks: DB connection, data freshness, counts, recent alerts
- JSON output for programmatic use
- Exit codes for monitoring integration

🚀 CI/CD PIPELINE:
- .github/workflows/ci.yml: Full CI/CD pipeline
- GitHub Actions / Gitea Actions compatible
- Jobs: lint & test, security scan, dependency scan, Docker build
- PostgreSQL service for integration tests
- 93 tests passing in CI

📚 COMPREHENSIVE DOCUMENTATION:
- AUTOMATION_QUICKSTART.md: 5-minute email setup guide
- docs/12_automation_and_reporting.md: Full automation guide
- Updated README.md with automation links
- Deployment → Production workflow guide

🛠️ IMPROVEMENTS:
- All shell scripts made executable
- Environment variable examples in .env.example
- Report logs saved with timestamps
- 30-day log retention with auto-cleanup
- Health checks can be scheduled via cron

WHAT THIS ENABLES:
==================
After deployment, users can:
1. Set up automated daily/weekly email reports (5 min)
2. Receive HTML+text emails with:
   - New trades, market alerts, suspicious timing
   - Weekly patterns, rankings, repeat offenders
3. Monitor system health automatically
4. Run full CI/CD pipeline on every commit
5. Deploy with confidence (tests + security scans)

USAGE:
======
# One-time setup (on deployed server)
./scripts/setup_cron.sh

# Or manually send reports
python scripts/send_daily_report.py --to user@example.com
python scripts/send_weekly_report.py --to user@example.com

# Check system health
python scripts/health_check.py

See AUTOMATION_QUICKSTART.md for full instructions.
