Resolves#72
## Description
This PR implements the theme toggle mechanism, client-side persistence, and comprehensive light mode style overrides for the mobile reader layout in **NexusReader**.
### Key Changes
1. **ThemeService & State Management**:
- Enhanced `ThemeService` with `InitializeAsync` and `ToggleTheme` using JS Interop.
- Synchronized theme state changes via `OnThemeChanged` event.
2. **Local Storage Persistence & FOUC Prevention**:
- Added client-side script in `App.razor` and MAUI `index.html` to instantly apply `.theme-light` from `localStorage` before prerendering/rendering to prevent a Flash of Unthemed Content (FOUC).
- Created `theme.js` containing JS helper methods (`themeInterop.isLightMode`, `themeInterop.setLightMode`) to interface with `localStorage` and `document.documentElement` class list.
3. **UI Theme Toggle**:
- Added a minimalist glassmorphic theme toggle button in the header of the `ReaderCanvas.razor` with dynamic transitions and icon morphing between sun and moon SVG icons.
4. **Light Mode Stylesheets Overrides**:
- Added detailed light mode scoped styles (`.theme-light`) for the `ReaderCanvas` and the bottom-sheet `GlobalIntelligence` AI chat panel, utilizing earthy gray text (`#2d2a26`) on warm paper-like backgrounds (`rgba(244, 241, 234, 0.95)` / `#faf8f5`) to maintain high-quality aesthetic consistency.
### Verification
- Solution built successfully without errors (`dotnet build NexusReader.slnx --no-restore`).
- Scoped CSS isolation checked and validated for both Web and MAUI contexts.

Reorganized the reader toolbar and layout grid to improve visual consistency and layout robustness in Focus Mode. Fixed outline SVG rendering bugs that caused icons to show as solid dots.
Closes#70

This pull request introduces the dedicated containerized infrastructure and configuration for deploying NexusReader's beta version in the Test environment.
### Summary of Changes
1. **Docker Infrastructure & Secrets**:
- **`docker-compose.test.yml`**: Configured dedicated database and auxiliary services (PostgreSQL 17, Qdrant, Neo4j) on isolated, non-standard ports to ensure zero conflict with the existing server configurations.
- **`.env.test.template`**: Provided an environment variable template showing required setups, including mandatory database passwords, API keys, and admin custom passwords.
- **`.gitignore`**: Excluded local `.env` files to prevent accidental commits of production or staging secrets.
2. **Database Hardening**:
- Configured Neo4j with basic authentication (`IDriver` instantiation uses basic auth when credentials are provided in configuration).
- Configured PostgreSQL to use mandatory authentication.
- Configured the admin seeder (`DbInitializer.cs`) to dynamically use `NEXUS_ADMIN_PASSWORD` from environment variables, falling back to a default password in local Development only.
3. **Feature-Flagged Restrictions**:
- **`appsettings.Test.json`**: Implemented `Features:AllowRegistration` and `Features:AllowPasswordReset` flags set to `false`.
- **Middleware Enforcement (`Program.cs`)**: Intercepts requests to `/identity/register` and `/identity/forgotPassword` (and their MVC/form variations) and rejects them with a `403 Forbidden` response in restricted environments.
- **OAuth Provisioning Guard (`Program.cs`)**: Blocks new account provisioning via Google OAuth callback by checking the `Features:AllowRegistration` configuration, redirecting users to the login page with a descriptive error.
- **UI Protection (`Login.razor`, `Register.razor`)**: Conditionally hides registration/password reset links and intercepts manual navigation attempts to `/account/register` by redirecting to login with a warning.

This Pull Request encapsulates all outstanding AI, Blazor InteractiveAuto lifecycle, pgvector, and Firefox authorization/session compatibility fixes.
### Key Accomplishments:
1. **Concurrent Request Deduplication (Option B):** Implemented a thread-safe active task registry in `KnowledgeService` that groups concurrent graph extraction queries for the same content, preventing duplicate AI calls completely.
2. **Resilience Strategy for Downstream Demands:** Extended the `ai-retry` resilience pipeline to automatically intercept and retry on temporary Google API `503 ServiceUnavailable` / `high demand` spikes.
3. **Interactive Graph Generation Guard (Option A):** Prevented server-side prerender-phase graph requests in the reader canvas component.
4. **Firefox Compatibility & Cookie Handler:** Implemented an authentication endpoint and hybrid hidden-form submission flow to solve login, registration, and logout redirections and cookies securely.
5. **Autoscrolling & Graph Exclusions:** Added concept-to-block smooth scrolling, active block badging, and filtered out markdown code blocks from being extracted as nodes.
All unit tests compiled and passed 100% cleanly.
