Add push monitor script deployment via SSH

- Add push_scripts.py with bash templates for heartbeat, disk, memory, cpu, and updates monitoring
- Modify kuma_client.py to return push token from created monitors
- Add deploy_push_script() to monitors.py for SSH-based script deployment
- Add heartbeat push_metric type to Claude agent suggestions
- Add /api/monitors/<id>/deploy-script and /api/monitors/deploy-all-scripts endpoints
- Update frontend to show push monitors with deployment status and retry buttons

Scripts are deployed to /usr/local/bin/kuma-push-{metric}-{id}.sh with cron entries.
