Fix model listing

Problem/Motivation

When we initially created the solution for getConfiguredModels, the Mistral API didn't have a detailed model listings page, however now it has a page that supports checking for if a model has tools calling, vision etc.

This means that instead of our pickings of models, we should now be able to dynamically update the list.

Another issue is that the list of models coming back from the model listing doesn't seem to come in an structured order, where better models feature first or something like that. Its very random - instead we should then order by readable name alphabetically.

Also the listing does not offer caching right now, meaning it does an API request every time we list it somewhere.

Proposed resolution

* List the models based on name.
* Add the capabilities based on the lists we get from the Mistral API.
* Cache the model list.
