Mirrors the custom-provider convention (``key_env`` names the env var holding the key; ``api_key_env`` accepted as an alias). Returns None when neither yields a non-empty value, letting ``resolve_runtime_provider`` fall through to the provider's standard credential resolution.

Legacy ``fallback_model`` entries are appended afterwards unless they target the same provider/model/base_url route as an earlier entry.
