feat: Mobile-First Layout Redesign & D3.js Graph Stabilization (#58)

This PR implements a comprehensive mobile-first design overhaul for the Reader, Dashboard, and Navigation layouts. ### Key Accomplishments 1. **Dynamic Viewport Synchronization**: Installed robust `ResizeObserver` listener on the client side with automatic reactive toggling of `platform-mobile`/`platform-desktop` CSS classes. 2. **Tab Controller & Visibility Fixes**: Refactored visibility constraints in `ReaderLayout.razor.css` to prevent layout clipping and DOM bloat. Standardized the mobile tab content selectors to ensure active views display perfectly. 3. **D3.js Graph Stabilization**: * Added checks to bypass resize callbacks when the graph container is hidden (`clientWidth <= 0` or `clientHeight <= 0`). * Guarded coordination ticks, node focus transformations, and zoom transitions against `NaN` parameters. 4. **Interactive Mobile UX Enhancements**: Optimized touch target sizing (44px target bounds) and interactive transitions for a state-of-the-art visual presentation. This has been successfully compiled and verified against the standard .NET 10 compilation gates. --------- Co-authored-by: Marek Jasiński <jasins.marek@gmail.com> Reviewed-on: #58 Co-authored-by: Antigravity <antigravity@google.com> Co-committed-by: Antigravity <antigravity@google.com>
