Type of Change

• Bugfix

Description

Original PR: #2802
Hotfix branch PR for this Main branch PR #2915

Currently, for a connector that returns processing status for full manual capture, if Psync is done later, status would always go from processing to partially_captured instead of succeeded.

Additional Changes

• This PR modifies the API contract
• This PR modifies the database schema
• This PR modifies application configuration/environment variables

Motivation and Context

How did you test it?

1. Create a merchant
2. Create a connector that returns processing status for single full capture. Then later gives succeeded after some time.
3. Create a payment with confirm = true and capture_method = manual.
4. Capture the payment fully. (status should be processing)
5. later do force sync. (status should be succeeded)
