Bring the functional tests of the released Varbase recipes into the Varbase functional testing suite

Problem/Motivation

The released Varbase recipes (events, news, podcasts, search, content and the AI recipes) each carry functional tests, but they only run against the recipe on its own. Nothing checks that they still pass on a full Varbase install.

Steps to reproduce

1. Open the varbase_project 11.0.x pipeline: none of these recipe scenarios run there.
2. The 16-eca-workflow-modeler folder is also missing from the test matrix, so it never runs.

Proposed resolution

Bring the recipe scenarios into the Varbase functional testing suite: fold them into the existing AI, workflow modeler and search folders, add new folders for events, news and podcasts, apply the extra recipes and their test content in the install job, and add matrix jobs so each job stays under 20 minutes. Scenarios that need a real AI provider key stay out and are listed in the merge request.
