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.

Resolves#52
This Pull Request introduces the **NexusSearchBox** search feature with premium unified styling, implements a robust **dynamic Qdrant collection auto-provisioning and batch-vector ingestion pipeline**, integrates a unified **Serilog logging infrastructure** for the Blazor Hybrid environment (MAUI), and resolves the **401 Unauthorized API header propagation error** inside mobile builds.
### 🚀 Key Implementations
#### 1. Premium `NexusSearchBox` & Semantic Search UI
* **NexusSearchBox Component:** Created an elegant search-as-you-type search box with smooth key navigation, quick-clearing, and seamless dynamic styling.
* **Unified Aesthetics:** Refactored the search box isolated styling to align perfectly with the dashboard's design system using glassmorphism, `--nexus-neon` token gradients, and smooth pulse/fade animations.
* **Semantic Search Integration:** Integrated semantic search query dispatching (`SearchLibrarySemanticallyQuery`) and wired up navigation seamlessly through the updated `ReaderNavigationService`.
* **Tests Hardening:** Added/adapted query assertions in `QueryTests.cs` to guarantee safe parameterization and error boundary mapping.
#### 2. Qdrant Collection Provisioning & Vector Ingestion
* **Dynamic Auto-Provisioning:** Implemented dynamic checking and lazy-creation of the `knowledge_units` collection using 768 dimensions and Cosine distance.
* **High-Performance Ingestion:** Optimized `ProcessKnowledgeUnitsAsync` with high-performance batch embedding generation using `_embeddingGenerator` and deterministic MD5 GUIDs for stable, duplicate-free upsertion.
* **Database Cache Clear Sync:** Integrated Qdrant collection deletion in `ClearCacheAsync` to ensure absolute consistency between the PostgreSQL database cache and vector database indices.
#### 3. Cross-Platform MAUI Logging (Serilog Infrastructure)
* **Serilog Integration:** Configured cross-platform Serilog routing in `SerilogConfiguration.cs`, streaming diagnostic logs safely across native platforms and the Blazor Webview container.
* **Interop Bridge:** Built `BlazorLoggingBridge.cs` to capture web console messages and pipe them directly to the native host logger.
* **Demo Interface:** Added an interactive `SerilogDemo.razor` sandbox under Pages.
#### 4. Resolving 401 Load Errors (Authentication Handler Flow)
* **Authentication Header Handler:** Implemented the `MobileAuthenticationHeaderHandler` to correctly extract, validate, and inject bearer JWT tokens into outbound API requests.
* **Configuration-based API Host:** Structured standard API URI routing to use clean configuration bindings in `appsettings.json`.

### 🧪 Verification & Build Status
* Run `dotnet build` from the solution root: Successfully compiled the full multi-targeted solution (`Liczba błędów: 0`).
* All unit and integration tests successfully executed and verified (`dotnet test`).
