Subject: fix: correct WebSocketPingInterval documentation and registry default
X-Git-Tag: ocpp-server@v4.0.0~15
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=06f62f72908f43e3ef9bcb1cd55310830d5a612f;p=e-mobility-charging-stations-simulator.git

fix: correct WebSocketPingInterval documentation and registry default

- Remove vendor-specific ChargingStation.WebSocketPingInterval entry
  from README (already listed under OCPPCommCtrlr per OCPP 2.0.1 spec)
- Use Constants.DEFAULT_WEBSOCKET_PING_INTERVAL in OCPPCommCtrlr registry
  entry instead of hardcoded '30' for single source of truth
