feat(share): enhance share page with mock data support and improved UI

- Updated the share page to display a more informative expiration time for red packets.
- Added a new empty state view to inform users when there are no shareable red packets available.
- Implemented mock data functionality for testing purposes, allowing for easier development and debugging.
- Enhanced the data loading logic to ensure the share list is correctly populated from the API response.
