fix: status goes from pending to partially captured in psync

[hrithikesh026]

Type of Change

• Bugfix

Description

Status would always go from Processing to PartiallyCaptured if force sync is done. Fixed it.

Other fixes and changes:

1. In payment_create, with confirm = true and capture_method = manual, if some amount_to_capture is sent in request body, it is updated in DB but the amount sent to connector will always be amount. So it is possible that amount_to_capture can be less than original amount but the original amount is sent to connector. Fixed it by requiring amount_to_capture to be equal to amount if confirm = true and automatic capture

2. surcharge amount wouldn't get updated in DB if connector returns error response. Fixed it.

3. amount_to_capture was not getting updated in DB if sent in payment_capture call. Fixed it.
