Stage 7: Rails 7.2 → 8.1 on Ruby 3.2.11

- Bump Rails to 8.1.3 (Ruby unchanged at 3.2.11, new gemset rails8-upgrade)
- config.load_defaults 8.1; merge app:update diffs for all environment files
- Remove routing-filter 0.7.0; replace with native scope '(:locale)' in
  routes.rb and default_url_options in ApplicationController
- Delete config/initializers/routing_filter_rails71_patch.rb
- Replace vendored TinyMCE 3.x (~200 files) with tinymce-rails ~> 8.3;
  migrate admin_interface.js from jQuery .tinymce()/advanced theme to
  tinymce.init(); add config/tinymce.yml; note: TinyMCE 7+ is GPL
- rails-i18n ~> 8.0 added explicitly (previously indirect dependency)
- awesome_nested_set, acts-as-taggable-on pinned to git main/master
  (gemspec activerecord < 8.1 ceiling; no functional incompatibility;
  repin to version once upstream releases updated gemspecs)
- globalize ~> 7.0, libxml-ruby ~> 5.0, nokogiri ~> 1.18, pg ~> 1.5
- sass-rails, coffee-rails, uglifier moved from :assets group to main
  (Sprockets 4 convention; :assets group no longer meaningful)
- Node: head, draft, lock_owner marked belongs_to optional: true
- Page: node, user, editor marked belongs_to optional: true
- Static assets in public/images/ and public/javascripts/ referenced via
  plain HTML tags; Rails 8 load_defaults raises on pipeline helpers for
  undeclared assets
- sessions_controller_test.rb: remove stale require and dead rescue_action
- users_controller_test.rb: assert button[type=submit] not input[type=submit]
  (Rails 8 button_to renders <button> not <input>)
- test_helper.rb: node.reload after children.create! (awesome_nested_set
  3.9.0 does not refresh parent in memory after callback)
- 129 runs, 339 assertions, 3 failures, 0 errors — identical baseline to 7.2
