Improve DiceDB Connection Status Reporting

[pawansoni007]

Problem

• Current /health endpoint only checks HTTP server, not DiceDB connection
• Users may see "healthy" server but get "Failed to fetch" errors with DiceDB

Proposed Solution

1. Create separate /dbstatus endpoint for DiceDB checks
2. Implement periodic DiceDB connectivity checks or
3. Use WebSockets for real-time status updates

Benefits

• Accurate DiceDB availability information
• Prevents user confusion and failed commands
• Improves user experience

Next Steps

1. Implement /dbstatus endpoint
2. Set up periodic DiceDB checks or
3. Add WebSocket for real-time updates
4. Update frontend to display DiceDB status in real time.
