- lib/forum.ts: getTopic/getPosts/countPosts aceptan includeDeleted (mods ven lo
  borrado); Post.deleted y TopicFull.deleted.
- API: PUT /api/forum/post restaura post (mod-only); moderate action 'restore'
  restaura tema (usa includeDeleted al leer el tema).
- UI: posts borrados atenuados con badge y botón Restaurar (PostActions);
  TopicModBar muestra banner + Restaurar tema cuando el tema está borrado.
- i18n es/en: Forum.restore, restoreTopic, deletedMark.
