v2.3.2: fix HelpView showing blank window (regression in v2.3.1)

In v2.3.1 the new 'Re-run Onboarding' button was added but the
self.setLayout(main_layout) line was accidentally indented into the
new _reopen_onboarding method body, so init_ui returned without
applying the layout. Result: F1 opened an empty dialog with no tabs.

Move setLayout back to the end of init_ui.

+### Fixed
+- **도움말 다이얼로그가 빈 창으로 표시되던 치명적 버그**
+  - v2.3.1에서 "온보딩 다시 보기" 버튼 추가 시 `self.setLayout(main_layout)` 라인이
+    실수로 `_reopen_onboarding` 메서드 안으로 들여쓰기되어 init_ui가 setLayout 없이 종료
+  - F1 누르면 빈 화면만 나옴 (탭 6개 모두 미렌더링)
+  - setLayout 호출 위치 복원 → 정상 표시
