Add dynamic configuration management with CONFIGURE/RESET control signals

[GaijinKa]

Description

This PR introduces configuration management capabilities to the control payload system by adding two new control signals: CONFIGURE and RESET. These signals enable dynamic runtime configuration updates for nodes without requiring a full restart.

The implementation allows nodes to receive configuration updates through the control payload mechanism, making the system more flexible and responsive to configuration changes during execution.

Key modifications and changes

• Add CONFIGURE and RESET variants to ControlSignal enum
• Extend ControlPayload with a data dictionary field to carry configuration parameters
• Implement update_config and reset_config method signatures in _node.py
• Add control signal handling logic in _node.py for CONFIGURE and RESET signals
• Update remote service to generate CONFIGURE signals on incoming configuration management requests
• Enhance passthrough identity node to properly propagate configuration updates
• Fix proto deserialization utilities in warp to support the new configuration data structure

Affected components

• Juturna core library: _node.py, control payload system
• Remote service: configuration request handling
• Warp: proto deserialization utilities
• Built-in nodes: passthrough identity node

Additional context

This change maintains backward compatibility as the data dictionary in ControlPayload is optional and defaults to an empty dictionary when not provided. Existing nodes that don't implement configuration updates will continue to work normally, ignoring CONFIGURE and RESET signals.
