Build error boundary with fallback UI

[FaveTeamz]

Overview

Wrap major page sections in React error boundaries to prevent full-page crashes.

Tasks

• Create a generic ErrorBoundary component
• Wrap Dashboard, Issues, and Admin pages
• Fallback UI shows error message and a retry button
• Log errors to console (or a future error tracking service)

Acceptance Criteria

• A thrown error in one section does not crash sibling sections
• Fallback UI renders with a useful message
• Retry button re-mounts the failed subtree
