/**
 * Voice routes — POST /api/voice/transcriptions (multipart) and legacy
 * POST /api/voice/transcribe (JSON/base64).
 *
 * The endpoints share one execution path that:
 *   1. Runs the configured STT provider and fallback chain
 *   2. Optionally runs LLM refine on the raw transcript
 *   3. Returns { raw, refined?, language }
 *
 * LLM refinement is opt-in through `voice.input.refinement`.
