fix: remove non-functional soft retry and simplify ErrorBoundary

- Remove removeFailedChunkScripts() — nothing marks scripts with
  data-failed and the bundler caches rejected promises, so soft retry
  was a no-op that misleads users
- Remove Retry button; keep Reload Page + Back Home for all errors
- Remove unused app.error.retry locale key from all 8 locales
- Evaluate navigator.onLine directly in render instead of caching in
  instance field, so error UI always reflects current network status
- Limit handleOnline auto-reload to chunk load errors only, preventing
  data loss from indiscriminate reload on render errors
- Remove offline event listener (no longer needed without isOnline cache)
