Refactor view handling and keybinding API

Move the `View` enum to a dedicated module and implement `Widget` for `&App` there. Rename `default_view_keybindings` to `default_keybindings` and adjust its signature. Redesign `KeybindingsWidget` to accept an explicit list of bindings instead of a `View`. Update imports, function signatures, and rendering logic across the codebase to reflect these changes.
