Traffic Portal integration tests strict compilation mode

[ocket8888]

What does this PR (Pull Request) do?

• This PR is not related to any Issue

This PR enables certain strict compilation options for the Traffic Portal integration test. Specifically, it sets:

{
    "strict": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "noImplicitThis": true
}

It does not, however, enable the noImplicityAny compiler option, because the test data is not currently type-safe, and changing that would be a multi-thousand-line change in its own right.

Which Traffic Control components are affected by this PR?

• Traffic Portal

What is the best way to verify this PR?
