Fix: Improve RPC error handling and routing

- Changed from rpcApp.use to rpcApp.all for better route handling
- Added proper error handling with try-catch
- Return 404 for unmatched routes instead of calling next()
- Return 500 for internal server errors
- Improves RPC endpoint reliability and debugging
