 //	@description	MeshCore network observation backend. Ingests LoRa packets from MQTT brokers, stores in PostgreSQL, and streams live events via WebSocket.
 //	@description	REST requests share a configurable per-client rate limit (default 300/minute and a 300-request one-second burst cap). Exceeded limits return HTTP 429 with error.code=rate_limited and a Retry-After header in seconds. CORS preflights and WebSocket upgrades do not consume this API budget.
 //	@description	WebSocket upgrade attempts at /ws have a configurable per-client limit (default 10/minute, including failed handshakes). Rate exhaustion returns HTTP 429 with Retry-After before upgrade. An accepted socket exceeding the concurrent cap closes with code 1013 before hello; established connections remain open.
