feat(server): go.mod + config + modèles de données

Initialise le module Go github.com/user/nanometrics/server avec toutes
les dépendances (SQLite, gorilla/websocket, paho.mqtt, prometheus,
imaging). Ajoute config.go (Load/Default via env vars) et models.go
(AgentMetrics, SmartMetrics, Agent, AgentConfig, ServerConfig, WSMessage).
