Rooms and push subscriptions now survive server restarts via JSON files
on a Docker volume. Stale participant cleanup skips users who have
active push subscriptions — they remain in the room and can still be
pinged for location and notifications when offline.

Manual "Ping All" now sends `manual: true` flag through WebSocket and
push channels. Receiving clients vibrate and respond with a one-shot
getCurrentPosition() regardless of sharing toggle. Auto-periodic 60s
pings stay silent and only respond if sharing is enabled.
Also fixes: SW cache invalidation (v2→v3), navigation requests now
network-first, sync server lastSeen uses ISO strings, Dockerfile
includes verify-token.js.
