Route image model tests to /api/v1/images/generations and STT to /api/v1/audio/transcriptions instead of forcing all non-embedding models through chat completions. Adds kind-aware pingModelByKind, hf->huggingface alias, and silent WAV sample for STT reachability. Scoped to dashboard/internal model testing only; runtime inference routing is unchanged.
