[client] Check the client status in the earlier phase (#4509)

This PR improves the NetBird client's status checking mechanism by implementing earlier detection of client state changes and better handling of connection lifecycle management. The key improvements focus on:

  • Enhanced status detection - Added waitForReady option to StatusRequest for improved client status handling
  • Better connection management - Improved context handling for signal and management gRPC connections• Reduced connection timeouts - Increased gRPC dial timeout from 3 to 10 seconds for better reliability
  • Cleaner error handling - Enhanced error propagation and context cancellation in retry loops

  Key Changes

  Core Status Improvements:
  - Added waitForReady optional field to StatusRequest proto (daemon.proto:190)
  - Enhanced status checking logic to detect client state changes earlier in the connection process
  - Improved handling of client permanent exit scenarios from retry loops

  Connection & Context Management:
  - Fixed context cancellation in management and signal client retry mechanisms
  - Added proper context propagation for Login operations
  - Enhanced gRPC connection handling with better timeout management

  Error Handling & Cleanup:
  - Moved feedback channels to upper layers for better separation of concerns
  - Improved error handling patterns throughout the client server implementation
  - Fixed synchronization issues and removed debug logging
