Enhance WebSocket and API documentation; implement connection protection features

- Added a note in the HTTP API documentation regarding the non-guaranteed sequence of price levels in order book responses.
- Updated WebSocket documentation to include a connection duration limit and a note on local sorting requirements for price levels.
- Introduced connection event handling in the ExchangeAdapter interface, allowing for disconnection and reconnection events.
- Implemented connection protection logic in the StandxExchangeAdapter and MakerPointsEngine to manage order states during connection disruptions.
- Enhanced the StandxGateway with methods for querying open orders and forcefully canceling all orders, improving reliability during network issues.
