Update Retell LLM

Change fields on a Retell LLM's draft version.

PATCHhttps://api.tried.com.au/update-retell-llm/{llm_id}

Merges the fields you send over the latest version and validates the result, including the prompt limit and knowledge base IDs. If the latest version is published, the change is saved as a new draft at the next version number. Arrays such as general_tools and states are replaced whole.

Agents that reference the LLM without a pinned version use the latest version, so drafts take effect on unpublished agents and in the playground right away.
