Describe this PR

What is the problem we're trying to solve

We need to deploy this API to new housing-pre-production account in order to complete the MTFH/TA backend setup in that environment.

What changes have we introduced

1. Add Terraform resources for pre-production. This includes parameter store value dependencies on top of the existing, production based, configuration
2. Add Terraform and code deployment workflows for pre-production. Terraform workflow requires manual approval to run but the code workflow runs automatically. This ensure pre-production is always in line with production
3. Remove the unnecessary policy that's stopping deployments from working when using Serverless V4 against new accounts. The policy is not required for the Lambda.
