Add Members (Pre-add)

Pre-add users to a Space as pending-activation members and send them an invitation email. This is used in Designated Space Mode before initiating OAuth authorization.

How it works: 1. Call this endpoint to pre-add the target users (status: pending activation). An invitation email is sent to each user. 2. Initiate OAuth authorization with both space_id and login_hint (see Authorization Endpoint). 3. When the user logs in on the Consent page and clicks Agree, their membership is automatically activated.

If you skip this step: Users cannot enter the designated Space through the OAuth Consent page — authorization will be rejected with access_denied.

Idempotent: If the email is already a pending-activation or active member of the Space, the call succeeds without creating duplicates or re-sending invitation emails.
