Additional Changes

• [ ] This PR modifies the database schema
• [ ] This PR modifies application configuration/environment variables

Motivation and Context

Note : 1)In the status mapping for the state Ok, -Authorize flow => Authorized -All other flows (Capture, Cancel, AutoCapture, Refund) => Processing.

2)In the response, we get two connector transaction IDs: -order_id => remains the same for further actions regarding that transaction.. -transaction_id => changes for every subsequent action (cancel, refund, capture, partial refund). -Both order_id and transaction_id are used for further actions (Psync, Cancel, Rsync, Refund, Capture), which should be passed in the URL. -We are storing the order_id in the connector_metadata. The transaction_id is stored in the connector_transaction_id once the payment has been captured, until then it is stored in the connector_metadata.
