Add is_byok flag to every LLMError's details dict returned from
handle_llm_error across all providers (OpenAI, Anthropic, Google,
ChatGPT OAuth). This enables observability into whether errors
originate from Letta's production keys or user-provided BYOK keys.
The rate limit handler in app.py now returns a more helpful message
for BYOK users ("check your provider's rate limits and billing")
versus the generic message for base provider rate limits.
