- New /@handle route (channel.handle name) that maps to UserController@channel,
so YouTube-style profile URLs work. Handle is the existing username
slug for now; a dedicated `handle` column can land later if we want
the two to diverge. {handle} is constrained to [A-Za-z0-9][A-Za-z0-9._-]*
so arbitrary paths don't match this route.
- Composer on the Wall tab used Auth::id() === $user->id directly,
which bypassed the $isOwner flip-to-false that preview-as-visitor
does. The composer now also checks !$preview so previewing an
owner's channel hides the post box as a visitor would see it.
