ROX-28461: Add change cloud_account and subscription_Id admin endpoint

• Documentation added if necessary (i.e. changes to dev setup, test execution, ...)
• CI and all relevant tests are passing
• Add the ticket number to the PR title if available, i.e. ROX-12345: ...
• Discussed security and business related topics privately. Will move any security and business related topics that arise to private communication channel.
• Add secret to app-interface Vault or Secrets Manager if necessary
• RDS changes were e2e tested manually
• Check AWS limits are reasonable for changes provisioning new resources
• (If applicable) Changes to the dp-terraform Helm values have been reflected in the addon on integration environment

There's already a PatchBillingParameters endpoint

unfortunately, PatchBillingParameters will not work when there is deleted subscription and AMS will simply return an error. I had to manually create a new subscription for the account with deleted one and we need new endpoint which will only update subscription_id and AWS account
