feat: Extend 1-minute data retention from 4 weeks to 1 year

- Updated lib/maintenance/data-cleanup.ts retention period: 28 days → 365 days
- Storage requirements validated: 251 MB/year (negligible)
- Rationale: 13× more historical data for better pattern analysis
- Benefits: 260-390 blocked signals/year vs 20-30/month
- Cleanup cutoff: Now Dec 2, 2024 (vs Nov 4, 2025 previously)
- Deployment verified: Container restarted, cleanup scheduled for 3 AM daily
