List Catalog Provider Models
List all models available for a given provider.
Returns each model's display name, content type, live `voice_count` (the
number of platform voices catalogued under that model), and a `controls` map
describing the canonical provider-agnostic parameters supported by the model
(e.g. speed, stability). Also includes `config_schema` for back-compat — new
integrations should prefer `controls` as the authoritative parameter
description. Each item includes a HATEOAS `voices` link to the paginated
voice list for that model. Returns 404 if the provider is not recognized.
