PL/pgSQL pre-validates column/table references in static SQL statements inside DO blocks before evaluating IF/RETURN guards. This caused migrations 0010-0061 to fail on fresh databases where the canonical schema uses `providers`/`provider_id` instead of `llm_providers`/ `llm_provider_id`. Wrap all SQL that references potentially non-existent old schema objects (llm_providers, llm_provider_id, tts_providers, tts_models, etc.) in EXECUTE strings so they are only parsed at runtime when actually reached.
