litellm: re-index models with local_/proxy_/direct_ prefixes + scaffold OpenAI+Gemini

Backend-prefix taxonomy so the Open WebUI picker is self-documenting and a
model name can't lie about where it routes:
  local_*  -> Anvil/Ollama (free)        e.g. local_qwen2.5-72b
  proxy_*  -> Claude via Meridian/Max     e.g. proxy_claude-sonnet-4-6
  direct_* -> metered OpenAI/Gemini       e.g. direct_gpt-4o, direct_gemini-2.0-flash

Drops the redundant -max suffix (proxy_ already implies Max). api_base is now
emitted only when a model defines it, so direct_* hit the provider default
endpoint instead of Meridian. direct_* are SCAFFOLDED (no live keys): litellm.env
writes a placeholder so the proxy boots; deploy.sh pulls OPENAI_API_KEY/
GEMINI_API_KEY from Infisical /meridian if present (non-fatal). They 401 until
real keys land.
