LG-7819: Modify enrollment creation CLI tool to create enrollments in USPS API

[NavaTim]

🎫 Ticket

LG-7876

🛠 Summary of changes

• Add new env var flag CREATE_PENDING_ENROLLMENT_IN_USPS to dev:random_in_person_users task
  • Creates enrollments via the USPS API if that is configured for the application

📜 Testing Plan

1. Update application.yml config:
   • Set usps_mock_fallback to false
   • Set values corresponding to a sandbox environment for the following:
     • usps_ipp_root_url
     • usps_ipp_username
     • usps_ipp_password
     • usps_ipp_sponsor_id
     • usps_ipp_client_id
2. If you created users with the dev CLI tools before, then make sure they don't have pending enrollments, for example:

echo 'ActiveRecord::Base.connection.execute("TRUNCATE in_person_enrollments RESTART IDENTITY")' | bundle exec rails console

3. Run the command:

# Create one user and configure a pending enrollment with corresponding USPS records
bundle exec rails dev:random_in_person_users NUM_USERS='1' SCRYPT_COST='800$8$1$' CREATE_PENDING_ENROLLMENT_IN_USPS='1'

If you want to see more details of the USPS IPPaaS requests, then you can temporarily add a line like the following to UspsInPersonProofing::Proofer.faraday. DO NOT do this in a deployed environment where the data could be ingested into logs.

conn.response :logger, nil, { headers: true, bodies: true }

Looks good. Left a couple suggestions, none blocking

A comment here would aid readability, something as simple as

# Convert index to a string of letters to be a valid last name for the USPS API

Do we need to worry about duplicates across multiple runs?

[NavaTim]

Duplicates are expected, and that's fine.
