Subject: [PATCH] fix: filter channel team task events from web UI chat

Admin users were seeing team task notifications from other channels
(Discord, Telegram, Lark) in their web UI chat due to bypassing the
UserID event filter. Added channel check to handleTeamTaskEvent matching
the existing pattern in handleAgentEvent.
