0xallam 1473fc7336 Use validate_environment to resolve provider env var
Naively uppercasing the routing prefix breaks for providers whose
LiteLLM env var name doesn't match the prefix verbatim:
  together_ai/...  needs TOGETHERAI_API_KEY  (no underscore)
  perplexity/...   needs PERPLEXITYAI_API_KEY

Ask LiteLLM directly via litellm.validate_environment(model=...) which
env vars it consults for the chosen provider, then setdefault each one
to LLM_API_KEY. This is the SDK-blessed lookup and stays correct for
every provider LiteLLM supports without a hand-maintained name map.

Lowercase the routed model name before lookup so mixed-case user input
(e.g. Together_AI/...) still resolves.
