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`).

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`).
