refactor: common util package, ESL/AMI/security fixes, Prometheus metrics
Backend stability and security improvements:
* internal/util/ — common RandomHex helper, removed 3 duplicates
* ESL: deduplicated readMessage (locked/unlocked), net.JoinHostPort for IPv6
* AMI: synchronous reconnect() in readEventsLoop, net.JoinHostPort for IPv6
* Auth: /api/auth/refresh accepts Authorization header only (no ?token=)
* decodeJSON: http.MaxBytesReader(1<<20) body limit
* Trunks: gatewayParams() uses configured ESL.GatewayPrefix
* Config: jwt_secret_env env-var fallback
* FSCollector: time.After → time.NewTimer with defer Stop
* Monitoring: Prometheus counters (route_requests, nodes_total/healthy, uptime)
* go fmt pass across all internal/ packages

feat: metrics agent for FreeSWITCH and Asterisk nodes
- pulse-lets-go-agent: collects metrics from PBX nodes via ESL (FreeSWITCH) or AMI (Asterisk)
- AMI client (raw TCP) for Asterisk Manager Interface
- Collector interface: collect, connect, subscribe hangup events, close
- FreeSWITCH collector: show channels, max_sessions, idle_cpu
- Asterisk collector: CoreShowChannels, CoreSettings
- System collector: /proc/loadavg, /proc/stat (CPU idle)
- Failure tracker: sliding window for call_failure_rate
- NATS publisher: pulse.metrics.<node_id> every 5 seconds
- Graceful shutdown, retry logic (5 failures → status=down)
- Template configs for UC nodes (Asterisk) and ses-sip (FreeSWITCH)
