fast startup config should serialize

Error message

fast startup config should serialize

What it means

injection_script_with_settings serializes the fast-startup feature flag (fast_startup_config) into the injected script globals; this expect-style error fires if serde_json fails. Serializing a boolean flag is infallible, so the error marks an internal invariant breach.
