Add Qubitro Integration

Description

This PR adds native Qubitro integration to ChirpStack to create a true no-code experience for users connecting ChirpStack to Qubitro Cloud. While Qubitro already provides a UI-based configuration using ChirpStack's HTTP integration, this native integration eliminates all manual configuration steps and provides a seamless bridge between ChirpStack and Qubitro Cloud.

Why This Integration?

The goal is to provide the best possible no-code experience for users of both platforms:

• For ChirpStack Users: Easy access to Qubitro's cloud-based data visualization and analytics
• For Qubitro Users: Zero-configuration device synchronization from ChirpStack
• For Everyone: Simplified IoT data management without writing any code

Instead of manually configuring HTTP webhooks, headers, and authentication, users can now:

1. Click "Add Integration"
2. Enter their Qubitro Project ID and Webhook Signing Key
3. Start seeing their data in Qubitro Cloud immediately

Features

• One-click setup with Project ID and Webhook Signing Key
• Automatic synchronization of:
  • Device data (uplink)
  • Join events
  • Acknowledgments
  • Device status
  • Location data
  • System logs
• Secure webhook authentication
• Built-in error handling and logging

Implementation Details

• Wraps ChirpStack's HTTP integration with a dedicated Qubitro configuration UI
• Follows ChirpStack's integration patterns for consistency
• Implements all necessary endpoints in Protocol Buffers
• Provides Rust backend for secure webhook communication
• Includes React components for seamless UI integration

Technical Benefits

• Simplified configuration within ChirpStack
• Automatic header management
• Proper error handling and validation
• Better user experience without leaving ChirpStack's interface

Development Notes

We've implemented this integration following ChirpStack's best practices. While we encountered some challenges with the local development environment, we're committed to:

• Providing any necessary adjustments
• Adding additional features if required
• Working with the ChirpStack team to ensure the integration meets all standards
• Helping with testing and validation

Checklist

• Implementation follows ChirpStack patterns
• Error handling and logging implemented
• Test coverage included
• Documentation complete
• Local testing (pending environment setup)

Thank you for the feedback. We’ve pushed one more update.

The tests are failing because of formatting errors. Could you please check? (cargo fmt should fix these). I'm looking forward to review this pull-request, but could you please first complete the local testing to perform an end-to-end integration?
