refactor: enhance error handling and performance tracking across components

- Improve localStorage access in ActivityFeed, ChatWidget, and AdminPage with try-catch blocks to handle potential errors gracefully.
- Update performance tracking in AnalyticsProvider and analytics.ts to ensure robust error handling and prevent failures from affecting user experience.
- Refactor Web Vitals tracking to include error handling for observer initialization and data collection.
- Ensure consistent handling of hydration mismatches in components like BackgroundBlobs and ChatWidget to improve rendering reliability.
