Keep the WebSocket alive: heartbeat + reconnect-on-wake
The mempool WS sends no periodic traffic on a track-addresses-only
subscription, so a half-open connection (died without firing onclose) went
undetected and updates fell back to the slow poll. Add:
- ping every 15s ({action:'ping'} -> pong); if no message for 45s, force a
reconnect (handles half-open sockets).
- reconnect + refresh on tab refocus (visibilitychange) and network 'online'.
