fix(auth): enforce authorization checks across API and Livewire components

- Add authorization checks to API controller endpoints (view, create, update, delete)
- Wrap Livewire component methods with try-catch for consistent error handling
- Add AuthorizesRequests trait to components requiring authorization checks
- Ensure all sensitive operations verify user permissions before execution
- Implement unified error handling with handleError() helper function
