GenAI.Provider.Media.OpenAICompat (Noizu Labs, GenAI Wrapper v0.3.2)

Shared OpenAI-compatible media-generation calls (ADR-016), parameterized by base_url + API key so the OpenAI providers and the LiteLLM proxy providers share ONE definition of each endpoint's request build + response decode (dmitri's "one definition" principle):

image/3 - POST {base}/v1/images/generations -> b64_json image bytes
speech/3 - POST {base}/v1/audio/speech -> raw audio bytes (TTS)
transcription/3 - POST {base}/v1/audio/transcriptions (multipart) -> transcript (STT)

Each returns the shared media contract {:ok, %{data, mime, meta}} | {:error, term}.
