feat(kaiqiu): add match nums and view count with Redis caching

- Extract 'nums' (号码) and 'see' (查看次数) from event page content.
- Include extracted data in the `IEventInfo` structure for display.
- Implement Redis caching for event details (key: `my-kaiqiuwang:event-info:${eventId}`).
- Cache strategy: Store result for 60 seconds, or refresh if cached data shows timeout errors or force flag is set.
- Reduces redundant external requests and improves response reliability.
