Implement Nonce Request Interface for Flexible Client Interactions

Original Task

Design Nonce Request Interface

Summary of Changes

This pull request introduces a new interface for nonce request handling, providing a flexible and type-safe approach to generating nonces across different client types.

Acceptance Criteria

Interface defines get_nonce() method with clear return and error types
Abstract method includes provisions for different client types
100% code coverage for interface definition
Interface documentation explains usage for each client type
Unit tests validate interface contract and error handling

Tests

• Verify get_nonce() method returns expected nonce type
• Confirm error handling for different client scenarios
• Validate interface works across multiple client implementations
• Ensure complete code coverage for interface definition
