AI functions (flashcards) promt

Allow to specify a custom prompt for AI functions. At the moment it is “all or nothing”, i.e. if there are some issues/misunderstands AI just does not work. Like using German notes and creating flashcards some of the are English. Could be solved with an additional custom prompt.
This will also allow to adapt the kind of questions, the style of the questions and answers and much more. Assuming you use some ChatGPT or similar in the background it would be great to add an optional custom prompt.
