Background task spawned on server startup: every 15 minutes, checks opt-in
status, builds anonymous health report (node ID hash, version, uptime,
CPU/RAM/disk %, container states, recent alerts), saves to disk, and POSTs
to TELEMETRY_COLLECTOR_URL env var if configured. Non-fatal on failure.
Fixed FiredAlert field references (kind not rule_type, timestamp not
fired_at) in both monitoring and analytics modules.
