[ENGA3-520]: Fixed the issue of FPX redirecting to cart page with invalid order status. Also added a delay in redirect process before fetching charge status.

1. Objective

Fixed the issue of FPX redirecting to cart page with invalid order status. Also added a delay in redirect process before fetching charge status.

Jira Ticket: #520

2. Description of change

Currently our plugin checks for processing and pending order state only. This caused issue when the webhook updated the order state to failed before customer reaching the redirect URL. So, we added a check for failed order state as well for Offsite.

Plus, we added a delay of 0.5 secs in Offsite and Threedsecure redirect flow before fetching the charge. This delay will be removed once the payment flow is changed in the backend.

3. Quality assurance

Configuration settings

Set webhook to Yes
Set Generate invoice at order status to Processing
