Gemini reached through the OpenAI-compatible endpoint returns
JavaScript-object-literal output — single-quoted strings, unquoted keys,
trailing commas — which strict JSON.parse rejects. The reservation list
then came back empty and the booking-import UI showed nothing (#1638).
Add a shared parseLenientJson() that tries strict JSON first and falls
back to JSON5 (which accepts exactly that relaxed superset), and route
both the OpenAI-compatible and Ollama-native parse paths through it,
replacing the two identical strict parsers.
