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.

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.
