Summary

🚚🛠️🧹

This pull request refactors and improves the code for handling payment and billing requests in the costcenter provider. It uses a common function GetUserDefaultNameSpace to get the user's default namespace, and removes or adds the kube_namespace variable as needed. It also moves some code from transfer.ts to pay.ts and fixes some minor errors.

pay.ts refactored
kube_namespace removed
code is more concise

Walkthrough

• Simplify and unify the logic for getting the user's default namespace by using the GetUserDefaultNameSpace function (link, link, link, link, link, link)
• Move the code for creating a transfer CRD from transfer.ts to pay.ts and delete the unused transfer.ts file (link)
• Add the missing import of the GetUserDefaultNameSpace function to the files that use it (link, link)
