feat(testing): Add synthetic user transaction bot simulating 24/7 campaign activity on Testnet #1364

🎯 Problem Statement & Impact

Continuous background synthetic transaction bot verifying Testnet end-to-end flow integrity.

Drives user acquisition, viral loops, social sharing, and automated campaign tracking.

🏗️ Technical Architecture & Affected Components

• Primary Component: frontend/ & backend/ (Growth Engine & Analytics)
• Integration Points: Ensures full backward compatibility across Soroban contracts, client SDKs, and backend services.
• Resource Management: Optimized memory utilization, efficient state storage keys, and extend_ttl rent management where applicable.

💻 Code Changes & Implementation Steps

1. Refactor key modules in frontend/ & backend/ (Growth Engine & Analytics) to fulfill standard code structure guidelines.
2. Implement explicit validation, error boundaries, and defensive checks.
3. Export clean TypeScript bindings or standard Rust/JS interfaces.
4. Verify end-to-end compatibility across all environment tiers (local testnet & mainnet).

🧪 Test Strategy & Verification Criteria

• Unit tests cover all primary control branches and edge cases cleanly.
• Integration tests verify contract/API boundaries without memory or balance leaks.
• Automated CI check passes clean linting, formatting, and security audits.
