…Suspense errors

- Added startTransition to React imports across multiple components
- Wrapped navigate() calls with startTransition(() => { navigate(...); })
- Fixed React 18 concurrent mode compatibility issues

Fixed 45 additional navigate() calls across 8 critical components:
- HeaderSection: 1 navigate call (notification navigation)
- DiscoveryContentSection: 7 navigate calls
- NotificationListSection: 20 navigate calls
- CommentItem: 4 navigate calls
- FollowingContentSection: 6 navigate calls
- Content: 5 navigate calls
- UserProfile: 1 navigate call
- MyTreasury: 1 navigate call

Total: 74 navigate calls now properly wrapped with startTransition
across 15 components to eliminate React Suspense errors.

This ensures all navigation state changes are deferred using React 18
concurrent features, preventing "component suspended while responding
to synchronous input" errors.
