Search models and add model empty dropdown

[allenz-crypto]

Dropdown is empty when searching for models, or when adding model from databricks:

that dropdown shows currently available models on your machine only.
if you configure more models, theyll show there.

You can also just type the model name in the text box on the RHS of where "Databricks" is in your screenshot. Even if it doesnt autocomplete, you can still use it so long as it exists! We do not currently dynamically fetch all model names for all providers, and databricks in particular takes model-serving endpoints, which can be any arbitrary string value (i.e. you could call your endpoint serving "gpt-4o", "my-gpt-model")
