Delete My Account — GraphQL

Deletes the authenticated admin's own account after re-confirming their password.

• Requires the caller's current password. A missing or incorrect password returns an errors entry; the account is left intact.
• Refuses to delete the last remaining admin.
• Distinct from Delete User, which deletes another admin and always refuses self-deletion.
• Deleting the account also invalidates the token that owns it.

No additional permission is required beyond authentication — the password confirmation is the gate.
