[Enhancement]: Track Tool Costs as Transactions

[leondape]

What features would you like to see added?

Currently, image generation can not be tracked and does not effect the credits.
I propose changing this and adding an image transaction collection like discussed in #6147.

Alongside with that I propose to have separate image credits, equivalent to the chat credits (though dollar-cents make a lot of sense there).

Image generation is quite costly. That way, a reasonable consumption can be easily enforced when deployed within organisations.
