refactor!: remove unused resizable components and enhance efficiency in critical areas

Remove outdated `ResizablePanelGroup`, `ResizablePanel`, and `ResizableHandle` components from the codebase. Optimize API error handling with anti-spam protection for repetitive errors. Update Dockerfile for streamlined builds, improve sitemap generation in `app`, and refactor lazy loading using `React.Suspense`. Refine services to support enhanced query parameters like `author`.
