feat: implement robust error boundaries and event handler resilience …

Closes #512

---

I have successfully implemented proper, robust Error Boundary wrap and try-catch event handler protection for both user-facing and admin panel Dark/Light Toggle components.

Here is a summary of the accomplishments:

Key Accomplishments
Resilient Event Handlers: Added try-catch blocks to the standard ThemeToggle component's click handlers. Any runtime exceptions are safely logged to the errorReportingService instead of crashing the UI.
Admin Theme Toggle Wrap: Separated context rendering logic in the AdminThemeToggle component and wrapped it in a secure ErrorBoundary.
Visual Fallback Component: Created AdminThemeToggleFallback with visual parity, accessibility options, and disabled states. If the context is unavailable, the component degrades gracefully and prevents any layout shifting in the Admin Panel Header.
Comprehensive Test Coverage: Added a click error catch test to theme-toggle.test.tsx and created a brand-new test suite at AdminThemeToggle.test.tsx to validate all boundaries, fallbacks, and logging behaviors.
