Stage 5: Rails 6.1 → 7.2 on Ruby 3.2.11

- Bump Rails to 7.2.3, Ruby to 3.2.11 (new gemset rails7-upgrade)
- pg pinned to 1.4.6 (bridge: Ruby 3.2 compatible, PostgreSQL 9.6 tolerant)
- acts-as-taggable-on → 12.x (Rails 7.2 + Ruby 3.2 support)
- awesome_nested_set → 3.7.0 (Rails 7.2 support, avoids 3.9.0 lft/rgt bug)
- globalize → 7.0 (Rails 7.x required)
- libxml-ruby → 5.x (Ruby 3.2 required)
- unicorn → 6.x; fix unicorn.rb: RAILS_ROOT→Rails.root, RAILS_ENV→ENV,
  File.exists?→File.exist?
- Add puma for development server
- Remove dead initializers: assets.rb, ruby2.rb, backtrace_silencers.rb,
  new_rails_defaults.rb
- Fix File.exists? → File.exist? in page.rb and authors_importer.rb
- Add routing_filter_rails71_patch.rb (restores params[:locale] on Rails 7.1+)
