Description of the changes, What, Why and How?

Fixes #1732.

When a message.new arrives for a channel that's in activeChannels but hasn't been watched yet, dispatchEvent throws. Happens during deep-link navigation (gap between client.channel(...) and .watch() resolving) and on screens that fetch via query({ watch: false }) and never watch.

The crash path is dispatchEvent → _handleChannelEvent → _countMessageAsUnread → muteStatus() → _checkInitialized(). _countMessageAsUnread is internal bookkeeping but was going through the public muteStatus() which gates on initialization. The throw escapes _handleChannelEvent and kills the rest of the dispatch cycle, so listeners and the offline-db handler for that event never run.
