Foro: editor rico ligero (barra de formato) en respuestas, temas y edición

- components/RichTextArea.tsx: barra de formato (negrita, cursiva, subrayado, tachado,
  enlace, cita, lista, código) que envuelve la selección del textarea en HTML;
  el HTML se sanea en el servidor con cleanPostHtml. Sin dependencias pesadas
  (evita CKEditor y no rompe el pipeline de saneado).
- Cableado en ReplyForm, NewTopicForm y PostActions (edición).
- i18n es/en: namespace Editor.

Verificado: build OK, /forum y home 200.
