Create Leads::GitlabCom::IterablesController

Summary

Create a new Leads::GitlabCom::IterablesController on CustomersDot to handle iterable lead creation for GitLab.com.

Problem

Iterable lead creation is currently handled in the monolithic trials_controller.rb via the create_iterable method. This needs to be extracted into a dedicated, REST-compliant controller.

Implementation Details

New Controller

File: app/controllers/leads/gitlab_com/iterables_controller.rb

Extract from trials_controller.rb

• create_iterable method logic
• Related validations and before_actions
• Iterable-specific error handling
• Any iterable-specific helper methods

Routes

Add to config/routes.rb:

namespace :leads do
  namespace :gitlab_com do
    resources :iterables, only: [:create]
  end
end

New endpoint: POST /leads/gitlab_com/iterables
