This Pull Request fixes the book upload dialog box's lack of visual feedback during the file ingestion process.
### Key Changes:
1. **Interactive `ingesting-state` Loading State**: Added a dedicated, beautiful neon-green loader that displays `Saving book to library...` with a pulsing neon spinner while the HTTP POST upload request is in flight. This cleanly replaces the form during ingestion, preventing users from clicking disabled/unresponsive inputs or submitting twice.
2. **Premium Glowing Button Loader**: Updated `.btn-loading` styling in `BookIngestionModal.razor.css` to use a high-contrast white-and-neon-green glowing spinner (`border-top-color: var(--nexus-neon)`) instead of an invisible black `#000` spinner on a faded, disabled dark button.
3. **Build & Test Verified**: Successfully verified that the entire solution compiles cleanly with 0 compilation errors (`dotnet build`) and that all unit/integration tests continue to pass perfectly (`dotnet test`).

Fixes#64
### Summary of Changes
1. **Extended `IEpubReader` & `EpubReaderService`**: Added `GetEpubResourceAsync` to handle binary data extraction of static assets (like images) from the EPUB archive.
2. **Added Client-Side HTTP Call**: Extended `WasmEpubService` to retrieve static resources from the server using the API client.
3. **Preserved and Sanitized Images**: Updated `ExtractParagraphs` and `SanitizeParagraph` to treat `<img>` tags as first-class citizens, preserving their `src` attributes and excluding them from sanitization stripping.
4. **Dynamic URL Rewriting**: Introduced a relative-to-absolute path resolution algorithm (`ResolveRelativePath`) and rewrote image `src` attributes to use the dynamic endpoint `/api/epub/{ebookId}/resource?path=...`.
5. **Registered API Resource Serving Endpoint**: Added the `/api/epub/{ebookId:guid}/resource` minimal API endpoint in `Program.cs` that maps requests directly to `GetEpubResourceAsync` and returns files with the correct MIME type.
6. **Added Unit Tests**: Created `EpubReaderServiceTests.cs` to verify all image extraction, path resolution, and sanitization/rewriting rules. All tests pass successfully.

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.

This pull request delivers a comprehensive mobile-first user experience overhaul for the NexusReader SaaS platform, specifically optimizing the Reader Canvas, D3.js Knowledge Graph representation, Dashboard card grid layout, and the application-wide navigation shell on mobile viewports (< 768px).
### Key Enhancements:
1. **Interactive Three-Tab Bottom Navigation**: Added premium, frosted glassy bottom-bar for mobile viewports to switch between standard reading, D3.js graph visual workspace, and structural concept reviews/quizzes.
2. **Contextual Floating Action Button (FAB)**: Introduced the AI Assistant FAB on mobile canvas layout with responsive animation, state-synchronization to trigger corresponding quiz views, and pulsing badge notification when new quizzes are dynamically generated.
3. **Adaptive D3.js Simulation & Rendering**: Integrated `setMobileMode(isMobile)` logic inside the D3 simulation engine, optimizing forces, rendering compact glyph pills, and installing auto-resize observers.
4. **Architectural & Native AOT Cleanliness**: Clean separation of layouts, fully scoped CSS configurations, functional-safe event orchestration inside `IReaderInteractionService`, and zero compiler errors.
