This PR stabilizes the Nexus Ingestion Engine by implementing functional service proxies for the Blazor WASM client and refining the backend infrastructure for real-time progress tracking and database compatibility.
### Key Changes
- **Infrastructure Stabilization**:
- Implemented production-grade `EbookRepository` with PostgreSQL `EF.Functions.ILike` support.
- Enforced `IsReadyForReading = false` state for newly added ebooks (resolves#35).
- Updated `SignalRSyncBroadcaster` to support targeted user messaging and ingestion-specific progress updates (resolves#37).
- **WASM Client Functional Proxies**:
- Replaced "Throwing" dummy services with `WasmEbookRepository`, `WasmSyncBroadcaster`, `WasmBookStorageService`, and `WasmEmbeddingGenerator`.
- These services proxy requests to the backend via a new set of Minimal API endpoints in `NexusReader.Web`.
- **Domain Refinement**:
- Added `IsReadyForReading` flag to the `Ebook` entity to manage background AI processing states.

This PR implements the Hub Navigation system and the Profile Dashboard, while resolving critical session synchronization issues.
### Key Changes
- **Hub Navigation**: Introduced `MainHubLayout` with a premium glassmorphism sidebar, providing access to Dashboard, Library, Concepts Map, and Profile.
- **Profile Dashboard**: Implemented a high-fidelity Profile page (#27) with learning metrics, AI token usage tracking, and system rank visualization.
- **Stability Fixes**:
- Resolved an infinite network loop on the `/profile` page by implementing request deduplication and in-memory caching in `IdentityService`.
- Added environment-aware guards to prevent illegal JavaScript interop calls during server-side prerendering.
- Implemented automatic session invalidation on `401 Unauthorized` responses to handle stale authentication states gracefully.
- **Reader Integration**: Added a "Return to Dashboard" option in the reader toolbar (#26).
