[FEATURE] Make payment create get tracker work with Provider/Processor (Platform context) #10488
Description
The current payment create → get tracker flow assumes a single merchant and does not naturally support Platform.
To enable further Platform work, we need minimal wiring so this flow can operate with the Platform context without completing the full feature. The intention is only to make the existing path behave correctly for both Platform and standard merchants, while deferring full Platform business logic and rule enforcement to later PRs.
