FQM-334: Fix response validation tests

[Jammjammjamm]

Summary

This branch removes the old response validation from the 2.2.1 server suite and fully transitions the response validation tests to rely on the logical models validation.

• Cards optional fields validation test removed
• Service response validation test validates the response against the base response logical model
• Individual response type tests find relevant responses and validate them against the particular logical model for that response type

Testing Guidance

The hooks tests should still pass when run against the client suite. The Specific Coverage Responses tests will still fail.

Anticipated Provider-side Test Impact

This update required two minor fixes to the mocked responses in the client suite:

• The suggestion was removed from the mock smart app launch card to align with the spec's intention
• A bug in the coverage information configuration handling was fixed. Previously, the response could contain an empty array in the systemActions field, which is not allowed in the spec, so this was changed to ensure that the systemActions field is removed if there are no actions.

Haven't been able to test it today due to terminology server issues, but here's my static code review
