📣 Summary

This PR implements the flow for activating the AI response generation feature and calling the actual generation endpoint

💭 Notes

• For this to work some changes were necessary in the current TabAnalysis flow, so we could have access to the automated feature as well.
• Now the manual_qual feature is created whenever a question is set and it's still not there. In the common flow it will happen once the first question is added. I chose that path instead of automatically creating the feature when TabAnalysis was opened, which i considered another viable option. This way we won´t create the feature unless the user really adds a qaQuestion.
• There's a verification logic to decide whether to create the advanced feature for the AI generation, to patch it or do nothing if all qaQuestions are already set for it. This is important in the case of new questions being added.
• Tags and Notes questions don't have Generate with AI enabled since it's not supported for them
• The actual API call to generate the answer is working, but the generated data is not being parsed and displayed in this PR. We will take care of this in a follow up work.

👀 Preview steps

2. have QA questions
3. have autoQAEnabled feature flag enabled (?ff_autoQAEnabled=true)
4. Press Generate with AI button in the analysis tab
5. 🔴 [on main] notice that this won't trigger any action
6. 🟢 [on PR] notice that this triggers activation of the feature for the existing questions and the API call for generating the answer with AI.
