Prompt engineering : merge the genai prompts templates in a "meta template"

Prompt engineering : Merge the genai prompts templates in a "meta template", to allow one call to genai services generate multiple texts with multiple embeded prompts.

For now, the behavior of a product text generation enrichment is handled on the completion phase and works as follow :

• for each product, there is a call on GenAiCompletionService.processProduct()
• This method calls the GenAiservice, with the Product, and the VerticalConfig, containing localized prompts templates, in a key value way. We can see configuration sample in the aiConfig properties, in the vertical tv.yml
• The GenAiservice then delegates handling to the AIService
• In the AIService, the doGeneration() will iterate over each internationalized aiConfig and delegates the generation to method generateProductTexts(), which effectivly do the call to SpringAI, for a given lang and a given key/prompt pair. The Product object is updated inside this method, it will be automatically persisted by the completion pipeline that calls the gen ai services.
• the generateProductText also handle prompt templatings through the spelEvaluationService. A note about AIService, which could be removed if all relevant genaiservices are moved to the GenAiCompletionService
• No big ideas on how to operate : Having a brief talk with a great AI Expert, the idea was given to ask for
• the LLM to generate the output in a json format, maybe even with the ai configuration provided to the LLM "as his".
