fix(websocket): fix PING timing - enable periodic PING during active traffic (IDFGH-16701)

[gabsuren]

Note

Stops resetting client->ping_tick_ms on read poll timeout so periodic PINGs proceed on schedule during active traffic.

• WebSocket client (components/esp_websocket_client/esp_websocket_client.c):
  • Adjust PING scheduling in WEBSOCKET_STATE_CONNECTED by removing client->ping_tick_ms = _tick_get_ms() after read poll timeout, preventing unintended PING delays.
