fix: add DateTime(timezone=True) to analytics.py (4 columns), update migration and port config

- analytics.py: 4 DateTime columns now timezone-aware (99 total, 0 remaining)
- Migration script updated with publish_records, content_metrics, optimization_insights
- Docker Compose: db port 5433, redis port 6380 (avoid conflicts with fischerx)
- .env files: DATABASE_URL and REDIS_URL updated to new ports
- alembic.ini: updated to localhost:5433
