Initial commit: Yodmon Yodeck→Zabbix bridge

- Yodeck API poller (every 10 min, paginated, 310 players)
- SQLite persistence (players + activity logs)
- SNMP v2c agent via net-snmp pass_persist
- Zabbix API auto host creation/update (6.0+)
- Flask web dashboard with live player status and log
- Docker deployment with persistent volume
- dev_server.py for local testing without Docker
