Start an acumatica oauth connect
Return the Acumatica consent URL for the resolved organization's self-hosted instance. clientId/clientSecret are the OAuth app registered on that instance; never echoed back. A multi-org credential must send an Organization-Id, Connection-Id or Entity-Id selector, or gets a 400. Call this from a browser with credentials (cookies) included: the callback that finishes the connect is bound to the session cookie this response sets, so it only completes for the same browser.
