Previously, the notice modal would automatically show every day even when
the notice content was empty, causing unnecessary user interruption.
This commit modifies the logic to:
- Check notice content before showing the modal
- Only display the modal when notice content exists and is not empty
- Add proper error handling to prevent modal showing on API failures
- Improve user experience by avoiding empty notice interruptions
Changes:
- Modified useEffect in Home component to fetch notice content first
- Added API call to /api/notice before setting noticeVisible state
- Added try-catch block for graceful error handling
- Only show modal when notice data is truthy and non-empty after trimming
