## Description
Routes the remaining system-only and legacy-sensitive LLM jobs through
feature-level model configuration, while preserving system credential
usage and usage-accounting behavior. This adds dedicated defaults for
help center article generation, onboarding content generation, query
translation, transcription, and search embeddings so these flows can be
configured per account without falling back to installation-wide model
settings.
