Stage 5 fixes: RouteWithParams removal, Globalize fallbacks, search stub, to_s(:db) → to_fs(:db), LockedByAnotherUser autoload, test environment config

- Remove safe_path helper and content_path shim from link_helper.rb
- Update all safe_path call sites in views to use named route helpers directly
- Fix Globalize fallbacks via config.i18n.fallbacks in application.rb, remove i18n initializer
- Stub Node.search returning none (search disabled pending PostgreSQL upgrade)
- Replace to_s(:db) with to_fs(:db) in node.rb, nodes_helper.rb, link_helper.rb, admin view
- Move LockedByAnotherUser to app/models/locked_by_another_user.rb for Zeitwerk autoloading
- Fix config/environments/test.rb: config.assets removed, cache_classes → enable_reloading,
  test_order removed, minitest pinned to ~> 5.25
- Fix config/environments/development.rb: cache_classes → enable_reloading
- Park search vector migration in doc/ pending PostgreSQL and plpgsql availability
