Search pane view with input, mode picker, result list

Replace the placeholder TextBlock with the real layout: a TextBox at
the top bound two-way to SearchPaneModel.SearchTerm (UpdateSourceTrigger
PropertyChanged so the orchestrator reacts on every keystroke once it
lands), a ComboBox bound to SearchModes / SelectedSearchMode, and a
ListBox that renders each SearchResult as three trimmed columns
(Name / Location / Assembly).
