Andrei 68e33712f1 feat: Add comprehensive error boundaries for graceful error handling ...

Implemented React error boundaries to catch and handle errors gracefully:

**Core Error Handling Components:**
- Created ErrorBoundary class component with error catching and logging
- Created specialized fallback UIs (MinimalErrorFallback, DataErrorFallback,
  ComponentErrorFallback, FormErrorFallback, ChartErrorFallback, ImageErrorFallback)
- Added withErrorBoundary HOC for easy component wrapping
- Created errorLogger service with Sentry integration placeholder

**Error Logging Service (errorLogger.ts):**
- Centralized error logging with severity levels (FATAL, ERROR, WARNING, INFO, DEBUG)
- Context enrichment (URL, userAgent, timestamp, environment)
- Local storage of last 10 errors in sessionStorage for debugging
- User context management (setUser, clearUser)
- Breadcrumb support for debugging trails

**App Integration:**
- Wrapped root layout with top-level ErrorBoundary for catastrophic errors
- Added NetworkStatusIndicator to main page for offline sync visibility
- Wrapped daily summary section with isolated DataErrorFallback
- Added error boundary to AI assistant page with ComponentErrorFallback
- Wrapped feeding tracking form with FormErrorFallback using withErrorBoundary HOC
- Protected analytics charts with isolated ChartErrorFallback boundaries

**Error Recovery Features:**
- Isolated error boundaries prevent cascade failures
- Retry buttons on all fallback UIs
- Error count tracking with user warnings
- Development-mode error details display
- Automatic error logging to service (when Sentry integrated)

Next: Integration with Sentry for production error tracking
