Redact access_key and ticket from WebSocket lifecycle INFO logs

Comienza por Client._connect() y _disconnect(), y después inspecciona la estructura existente del registro del ciclo de vida y de las pruebas de regresión. Se considera terminado cuando ambos mensajes INFO redacten únicamente los valores de access_key y ticket, manteniendo el resto del contexto de la URL, y websockets.connect() siga recibiendo la URL original exacta.

Problem

Client._connect() and _disconnect() log the complete WebSocket connection URL at INFO level. The URL returned by the Lark WebSocket endpoint contains sensitive access_key and ticket query values, so normal lifecycle logs can disclose credentials to stdout, journals, or downstream log collectors.

The current default-branch code passes the original URL directly to both log calls:

• logger.info(self._fmt_log("connected to {}", conn_url))
• logger.info(self._fmt_log("disconnected to {}", self._conn_url))

Reproduce / evidence

Using only fictional values, suppose _get_conn_url() returns:

wss://msg-frontier.example.test/ws/v2?fpid=493&access_key=access-key-test-value&service_id=33554678&ticket=ticket-test-value

After a connection and disconnect, the INFO messages include both access-key-test-value and ticket-test-value verbatim. The same original URL is also correctly required by websockets.connect(); the connection input itself must not be changed.

I searched current issues, pull requests, and default-branch code for msg-frontier, access_key, ticket, connected to, redact websocket URL, and sanitize URL query. I did not find an issue or PR that covers redaction of both WebSocket lifecycle log messages.

Required fix

Please redact only the values of the access_key and ticket query parameters before formatting the connection and disconnection INFO messages, while preserving the original URL for connection state and websockets.connect().

The log-safe representation should preserve non-sensitive query parameters and enough endpoint context for diagnostics. Ideally it should also preserve query ordering, repeated parameters, percent-encoding, empty/value-less parameters, and fragments except for replacing the two sensitive values.

Please add regression tests proving that:

1. neither lifecycle log contains the original access_key or ticket value;
2. non-sensitive URL context remains visible;
3. websockets.connect() receives the exact original URL; and
4. both connection and disconnection logs use the redacted representation.
