fix: restrict content-query by cap before pagination, filter hidden fields

Review fix round 1: content-query now excludes posts/statuses the user
cannot edit before querying (author restriction without edit_others_posts,
status filtering by edit_private_posts/edit_published_posts) instead of
only dropping them after fetching, and rejects unknown field/taxonomy
filters. content-types' not-found hint only lists editable types.
PostPresenter skips Pods password fields and readonly protected meta.
Query input gains search/terms length limits.
