Subject: [PATCH] fix(channels): restore bound logger in discord and websocket

PR introduced module-level logger in static methods, which drops
the channel context bound by BaseChannel.__init__. Revert to
self._channel.logger / self.logger to preserve log labels.

Also remove @staticmethod since these methods legitimately need
instance access (F821 was the real issue, not the logger source).
