Implement Web Client Nonce Retrieval with Enhanced Reliability

Original Task

Implement Web Client Nonce Retrieval

Summary of Changes

This pull request implements a robust nonce retrieval mechanism for the web client, focusing on reliability, performance, and minimal network overhead.

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 mechanism for failed requests
• Validate nonce caching functionality
• Perform branch coverage analysis
• Conduct performance testing for nonce retrieval time
