Implement Comprehensive Evidence Uniqueness Test Suite

Original Task

Create Integration and End-to-End Tests for Evidence Uniqueness

Summary of Changes

Added integration and end-to-end tests to validate evidence uniqueness validation mechanisms, ensuring robust handling of submission scenarios.

Acceptance Criteria

Create a test suite that covers all uniqueness validation scenarios
Verify that duplicate submissions are consistently rejected
Test concurrent submission scenarios to ensure thread safety
Measure and document performance impact of uniqueness checks
Achieve 95% test coverage across uniqueness validation components
Performance tests show validation overhead is within acceptable limits

Tests

• Test duplicate submission rejection
• Verify thread-safe concurrent submission handling
• Measure performance overhead of uniqueness validation
• Validate comprehensive coverage of uniqueness scenarios
