Stage 5 click-testing fixes

- Fix link_to :method → button_to for all PUT/DELETE actions
- Add button_to CSS reset to admin.css for visual consistency
- Fix admin layout: replace broken jquery/jquery_ujs pipeline refs with
  admin_bundle via sprockets; add sprockets-rails, jquery-ui-rails gems
- Add app/assets/javascripts/admin_bundle.js pipeline manifest
- Fix event_information helper: use safe_join to avoid double-escaping
- Fix nodes_helper: to_s(:db) → to_fs(:db) for event times
- Fix revisions view: eliminate nested forms; diff button uses vanilla JS
  to collect radio button values before POST
- Fix config/environments/development.rb and test.rb: cache_classes →
  enable_reloading
- Add routing_filter_rails71_patch.rb version guard
- Move LockedByAnotherUser to own file for Zeitwerk autoloading
- Fix Globalize fallbacks via config.i18n.fallbacks in application.rb
