refactor: Simplify Rails component loading and remove ActiveRecord configurations

Updated config/application.rb to load Rails components directly instead of using an array, enhancing clarity. Removed ActiveRecord-related configurations from spec/rails_helper.rb, as the application uses Couchbase instead of ActiveRecord, streamlining the test setup. This change improves maintainability and aligns with the application's architecture.
