For an integration whose `auth.kind` is `api_key`: store the end user's own key. It is checked first with the provider's own read-only check when the catalogue has one; a key the provider refuses is not stored (`CONNECTION_KEY_REJECTED`). It is encrypted like a connected account's token, replaces the end user's previous key for the integration, and is never returned. No confirmation step: your server supplies the key. At most 10 keys per minute per end user.

`PUT /api/v2/end-users/{endUserId}/connections/{integration}`
