fix: channels filter visible when channel feature disabled - WPB-24857

[johnxnguyen]

WPB-24857 [iOS] [Filters] Unsupported channels appear when selecting filters by user

Issue

Even when channels is disabled for the user, they are able to see the channel filter (from filter menu in iOS and Split View sidebar on iPadOS).

This PR conditionally shows the channels filter depending on the channels feature config state.

Testing

Log in to an account that doesn't have channels, assert no filter for channels is visible (both iPhone and iPad):
