get session analytics

Returns per-turn latency analytics for a session — where time was spent in the transcription → LLM → TTS → first-audio path for each conversational turn, plus session-level summary metrics. Analytics become available once the session has ended and the engine has delivered its session report; until then this endpoint returns 404. Analytics exist only for sessions where Anam runs the conversational pipeline (turnkey, custom LLM and ElevenLabs agent sessions) — LiveKit and audio-passthrough sessions never produce them. Message text is omitted unless includeMessages=true is passed and transcripts were enabled for the session. Anam-internal admin API keys may fetch analytics for sessions of any organization.
