feat(ui): Hub Navigation, Profile Dashboard and Auth Stability Fixes (#31)

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).
