refactor(stores): unify data sources pattern and extract BaseManager base class
- Add BaseManager/CachedManager base classes to eliminate duplicate cache logic - Add postListSources.ts with IPostListPagedSource interface - Add groupListSources.ts with IGroupListPagedSource interface - Refactor postManager to use CachedManager and Sources pattern - Refactor groupManager to use CachedManager and Sources pattern - Clean up duplicate methods in groupService.ts - Fix TypeScript errors and remove mock data
