refactor(admin): split controls + dsr/[requestId] pages

controls/page.tsx 840→211 LOC — extracted StatsCards, FilterBar,
ControlCard, AddControlForm, RAGPanel, LoadingSkeleton to _components/;
useControlsData, useRAGSuggestions to _hooks/; shared types to _types.ts.

dsr/[requestId]/page.tsx 854→172 LOC — extracted detail panels and
timeline components to _components/.
