Fixing Ollama (and other dynamicModel providers) (re: #259)

[ssmirr]

fixes #259.

the main bug effecting #259 is that MODEL_LIST did not include dynamicModels (for providers that support it). In fact dynamicModels were not fetched at all, meaning this is not only breaking Ollama provider, but also any other provider + model that uses dynamicModels.

that resulted in falling back to the DEFAULT_MODEL (i.e. claude-3-5-sonnet-latest) being selected as the currentModel because this condition always failed to find requested model:
https://github.com/coleam00/bolt.new-any-llm/blob/88700c24526bb5d722d48e51d0f2bb1cc77fb72a/app/lib/.server/llm/stream-text.ts#L51-L60

this PR constructs a list of dynamicModels by fetching it from all providers in parallel, and fixes MODEL_LIST to include those models as well.

let me know if you have any questions, and thanks for creating and maintaining this fork!

I do get errors in master version and it works after this fix

But I remember testing it before.
In reality there is this method below that does similar thing
initializeModelList

And its called in some places like
https://github.com/coleam00/bolt.new-any-llm/blob/main/app/components/chat/BaseChat.tsx#L134

In theory, after your change it can be removed
I like your solution better, should error less

Though I am already thinking that we should change how this works.
We should have dynamic models list per provider be called in lazy fashion when provider is called for the first time.
And it should probably be filtered/paged/searched or soemthing.
Providers like huggingface have a LOT of models in their model list.

But that is for future.

Here we do need this fix quicker as its a bug.

Can you remove initializeModelList completely from codebase and test?
