Subject: Fix tagged content aggregator, assets path, and add regression tests

- Replace tagged_with calls in Page.aggregate, TagsController, RssController
  with direct SQL joins (acts-as-taggable-on 3.5 broken on Rails 3.2)
- Fix Paperclip :path/:url to use plain :id format matching existing uploads
- Add proper regression tests for aggregator, tags, and rss controllers
- Fix assert_select assertions to target div.body div.article_partial

Subject: Rails 5.2 application fixes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Rename before_filter → before_action across all controllers
- Fix string conditions in validators to lambda syntax (node.rb)
- Fix publish_draft!: move staged slug/parent logic outside draft guard,
  use move_to_child_of for parent changes, add nil guard for no-op calls
- Fix update_unique_names_of_children: use parent_id traversal instead
  of lft/rgt descendants (awesome_nested_set 3.x lft/rgt update bug)
- Fix unique_path to return Array instead of String
- Fix Occurrence.delete_all syntax for Rails 5
- Fix Page.find_with_outdated_translations: use includes instead of all
- Fix outdated_translations?: use find instead of splat array
