chore: remove localHypermodeModels list and handle 404s properly instead in local dev

[kevinmingtarja]

Description

This PR adds meta-llama/Llama-3.2-3B-Instruct to the list of models available during local development.

Edit: This PR removes the localHypermodeModels list, so that we don't need to push new commits and version updates when making new models available for local dev.

Instead, we let the users specify any model they want, and if it's not available, our models gateway will return a 404, and the Runtime code will handle it accordingly.

Approved, but I really think we should just remove this list entirely. Let the user try any model. Fail with the appropriate HTTP code if it's not available, then handle that error accordingly. Then we won't need to push new versions to update the list of models.
