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 pull request implements **Central Package Management (CPM)** across the NexusReader solution to centralize package version definitions, improve package maintainability, and ensure security patch consistency. It also resolves compile issues in the mobile infrastructure and client projects.
### Key Changes
#### 1. NuGet Central Package Management (CPM)
- Created `Directory.Packages.props` in the solution root containing all solution-wide dependency versions (consolidating 48 packages).
- Pinned and secured `Microsoft.Bcl.Memory` to `v9.0.14` to resolve a known high-severity vulnerability (CVE-2026-26127).
- Stripped explicit `Version` attributes from `.csproj` files for the core library, web client, web host, UI shared, data access, and testing projects to inherit central version definitions.
#### 2. Mobile / MAUI Projects Stabilization
- **Workload Support & Locally Disabled CPM**: Disabled Central Package Management locally (`<ManagePackageVersionsCentrally>false</ManagePackageVersionsCentrally>`) in both `NexusReader.Infrastructure.Mobile.csproj` and `NexusReader.Maui.csproj` to preserve native MAUI workload package integration while cleanly referencing package versions manually.
- **Ambiguity Resolving**: Added using aliases for `FluentResults.Result` to eliminate compiler ambiguity conflicts between `Android.App.Result` and `FluentResults.Result` inside Android platform service implementations.
- **Missing Namespaces Fix**: Added explicit hosting imports (`using Microsoft.Maui; using Microsoft.Maui.Hosting;`) and ensured `Microsoft.Maui.Essentials` references resolve properly in the mobile context.
---
### Verification
- **Build**: Successfully built the entire solution with zero compilation errors (`dotnet build NexusReader.slnx --no-restore` -> `Liczba błędów: 0`).
- **Tests**: All 7 integration and unit tests run and pass successfully (`dotnet test NexusReader.slnx --no-restore`).

This PR provides critical stabilization, memory leak resolution, and security enhancements for the NexusReader application, specifically focusing on Blazor InteractiveAuto lifecycle safety, thread-safe automated authentication token refresh, and deduplication of active AI service queries.
### Key Enhancements
#### 1. Security & Lifecycle Stabilization (`AuthenticationHeaderHandler.cs` & `Library.razor`)
* **Secure Token Propagation (CWE-200)**: Modified the outbound delegating handler to only append JWT Bearer headers to trusted base origin requests matching the application's configured `NavigationManager.BaseUri`, preventing potential token leakage to external services.
* **Captive Dependency & Memory Leak Fix (CWE-400)**: Avoided capturing scoped dependencies in a singleton handler by wrapping the resolution of `IIdentityService` inside a dedicated, disposable `IServiceProvider` scope (`_serviceProvider.CreateScope()`).
* **Thread-Safe Automated Refresh**: Embedded a `SemaphoreSlim` lock around the automated `RefreshTokenAsync` renewal sequence to handle concurrent API requests gracefully without triggering duplicate token refresh attempts.
* **Pre-rendering Safety**: Deferred the secure book loading query in `Library.razor` from `OnInitializedAsync` to client-side `OnAfterRenderAsync(firstRender: true)` to avoid inevitable `401 Unauthorized` responses and logs during the server pre-rendering phase.
#### 2. Robust AI Request Deduplication (`KnowledgeService.cs`)
* **State Recovery Guards**: Enhanced the thread-safe `Lazy<Task<Result<KnowledgePacket>>>` deduplication map by adding thorough failure handling blocks. Active requests are guaranteed to be cleaned up (`TryRemove`) inside `finally` and failed results pathways, ensuring future retries can run immediately if an initial request encounters an error.
#### 3. Idempotent AI UI Fetching & JSRuntime Guards
* **Interactive Guards**: Added an `_isInteractive` check to `GroundednessBadge.razor` and `AiAssistantBubble.razor` components, deferring WebAssembly API executions and DOM updates to client-side `OnAfterRenderAsync`.
* **State Synchronization**: Integrated a synchronous `OnParametersSet` to properly reset groundedness badges when content changes.
* **Flicker Elimination**: Moved JSRuntime local-storage checks in `Home.razor` (for focus mode preferences) to `OnAfterRenderAsync(firstRender: true)`, resolving startup JSInterop exceptions and eliminating layout shifts.
### Verification Performed
* Mandatory build gate verified: `Kompilacja powiodła się.` with zero compile errors (`dotnet build NexusReader.slnx --no-restore`).
* Validated dependency resolution patterns and async safety (no `async void`).
