Implement Web Client Nonce Retrieval with Caching and Retry Mechanism

Original Task

Implement Web Client Nonce Retrieval

Summary of Changes

Developed a robust nonce retrieval system for the web client with advanced features including exponential backoff, caching, and error handling.

Acceptance Criteria

Web client successfully retrieves nonces from server endpoint
Implements exponential backoff for failed nonce requests
Caches nonces to minimize network calls
90% branch coverage for network request and error scenarios
Performance test: Nonce retrieval under 200ms for 95% of requests

Tests

• Verify nonce retrieval from server endpoint
• Test exponential backoff strategy
• Validate nonce caching mechanism
• Check error handling for network requests
• Measure nonce retrieval performance
