form definitions csv export feature test and implementation

Feature: Export Form Definitions as CSV

  Background:
    Given form definition "Form 1" with:
      | locked_at               | 2025-04-02T10:00:00                  |
      | locked_configuration_id | b9bff254-4877-4c3c-b813-bbf2645c547e |
    And form definition "Form 2" with:
      | locked_at               | 2025-04-02T11:00:00                  |
      | locked_configuration_id | d959e932-20db-4f9c-9521-65cba31d2bf4 |

  Scenario: Export form definitions as csv
    When I sign in as a user with all permissions
    And I browse to form_definitions list
    Then I see "Form 1"
    And I see "Form 2"
    When I click "CSV"
    Then I download a CSV with content:
      | Id     | Name   | Current configuration | Locked configuration | Locked at  | Created at | Updated at |
      | <UUID> | Form 1 | <UUID>                | <UUID>               | <ISO_DATE> | <ISO_DATE> | <ISO_DATE> |
      | <UUID> | Form 2 | <UUID>                | <UUID>               | <ISO_DATE> | <ISO_DATE> | <ISO_DATE> |


  csv do
    column :id
    column(:name) { |fd| fd.object.name }
    column :current_configuration_id
    column :locked_configuration_id
    column :locked_at
    column :created_at
    column :updated_at
  end

  when "<UUID>" then match(/^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$/i)
