stacks: add csm (Sesame Conversational Speech Model) to the TTS bench

Sesame CSM-1B via phildougherty/sesame_csm_openai — OpenAI-compat /v1/audio/speech, context-aware conversational speech (voice-agent layer, not a plain reader). Port 8201 on irv-ml1. Gated model: requires CSM_HF_TOKEN (license acceptance) — placeholder in .env.example, real token only in host .env.
