`POST /v2/subscriptions/cancel-cta-experiment/enroll`

## Request body

- EnrollCancelCtaExperimentDto
  - `trigger` 'settings_subscription_manage_show' | 'settings_payment_methods_remove_last_card' — Which entry point asks for the assignment — the Manage Subscription section, or removing the last saved card. Recorded on the assignment context.

## Response `200`

- CancelCtaExperimentAssignmentDto
  - `experimentKey` string, required
  - `variantId` string, nullable, required
  - `source` 'forced' | 'sticky' | 'fresh' | 'default', required
  - `assignedAt` string, date-time, nullable
