feat(skill-tests): add form-add + form-compile steps to platform integration tests

Now that ExtendedPresentation and InterfaceCompatibilityMode bugs are fixed,
platform integration tests can include full form generation:
- platform-config: form-add + form-compile for Catalog and Document forms
- platform-epf: epf-add-form + form-compile with elements/attributes/commands
- platform-cfe: form-add + form-compile for borrowed Catalog form
