feat: add OrcaRouter as a first-class LLM provider

Add OrcaRouter to the supplier registry so it can be selected as a
named provider in the model management UI, mirroring the existing
OpenAI/DeepSeek entries. The preset points at the OpenAI-compatible
endpoint (https://api.orcarouter.ai/v1) with a curated set of models,
and the provider is listed in the README provider tables.
