Fix connection timeout: use REST API for initial state load, increase WS timeout to 60s

Large HA instances with many entities cause get_states to exceed the 12s
WebSocket timeout. Now loads all states via /api/states HTTP endpoint first
(much more reliable for large payloads), with WebSocket get_states as fallback.
Also bumped WS send timeout from 12s to 60s for slow HA responses.
