feat: add Preset routes to API + patch for tool_call_id max length OpenAI error

patch for tool_call_id max length OpenAI

Separately - this PR patches a new error introduced by an update to the OpenAI API, where they now require tool_call_id to be <= 29 characters.

To fix this, the generate tool call ID helper function now trims a UUID to the max (OpenAI) length. For existing messages / Message objects, we now trim the strings at "runtime" (.to_openai_dict() time) to the max length.
