Provider prompt is not being used

Hi @ktpm,
thank you for this issue! I downloaded the module yesterday and set it up with Gemini, I'm having the same problem, the prompt entered in the provider is not supported!

Your patch works very well for me!

Thanks

Thanks for this; will keep this open for now but to note that likely soon will switch over to ✨ Fallback to ai_translate configuration Active which will provide a much more robust and consistent prompt management. Just need a blocker in AI Core module resolved first.

Actually this doesn't hurt to merge of course... will merge in the meantime, just letting coding standards run

Thanks!
