REDI-92: Views/XML renderer for the characters list (same MVI ViewModel)

Browse Source 
Add :feature:characters:presentation-views — a classic Fragment + ViewBinding +
RecyclerView/DiffUtil renderer driving the SAME CharacterListViewModel as the Compose
screen (obtained via Koin's by viewModel()), proving the presentation logic is truly
UI-agnostic. State is observed with viewLifecycleOwner.repeatOnLifecycle(STARTED),
one-time Events are collected, UiText is resolved via Context, and the binding is nulled
in onDestroyView. Coil loads avatars into ImageView with a circle-crop transform; the
module has no Compose dependency.

Paging scroll listener guards the empty-list case (lastVisible >= 0), uses a safe
layoutManager cast, and is removed in onDestroyView.
