Update network policy for all environments

[fergmac]

Describe the task
We have updated the allow same namespace network policy to be more detailed and provide the dev environment namespace for deployments. We need to make this dynamic for all environments.

Purpose
To successfully deploy the backend to each environment and allow communication between containers ie the backend and the database

Acceptance Criteria

• The backend container deploys successfully in all environments.

Additional context

• This namespace license plate should be passed in as a param from the .deploy workflow file to the openshift deployment yaml file for the backend
• we can use the vars.OC_NAMESPACE environment variable for the licence plate
• we can use the inputs.target for test and prod but we will likely have to check if we are in those environments and if not just use a default "dev"
