fix: use double-cast to resolve TS2352/TS2322 type errors

Named interfaces without index signatures cannot be directly cast to
Record<string, unknown>. Use `as unknown as` double-cast to satisfy
TypeScript strict mode for the AnyEntity[] and Dispatch casts in
ConfigDetail.tsx, and the Config -> Record<string, unknown> cast in
ConfigList.tsx.
