Create Leads::GitlabCom::UltimatesController

Summary

Create a new Leads::GitlabCom::UltimatesController on CustomersDot to handle trial-related lead creation for GitLab.com.

Problem

The trials_controller.rb#create method currently handles both lead creation and trial application. This needs to be separated - this issue extracts the lead creation portion into a dedicated controller.

Implementation Details

New Controller

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

Responsibilities:

• Handle trial-related lead creation for GitLab.com users
• Validate lead parameters
• Integrate with lead tracking systems (Marketo, Salesforce, etc.)
• Return appropriate success/error responses

Extract from trials_controller.rb

• Lead creation logic from create method
• Related validations for lead data
• Lead-specific error handling
• Any lead-specific helper methods

Important: Do NOT extract trial application logic - that stays in trials_controller.rb#create and will be moved by another epic.

Routes

Add to config/routes.rb:

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

New endpoint: POST /leads/gitlab_com/ultimates
