Create Comprehensive Tests for Fulfillment Escrow

[codebestia]

Description 📝

Develop a comprehensive test suite to validate the functionality of 'Fulfillment Escrow'. It is critical to ensure that all edge cases, unauthorized access attempts, state transitions, and overflow conditions are thoroughly vetted to prevent smart contract vulnerabilities in the crowdfunding ecosystem.

Proposed Steps 📝

• Set up a dedicated test file tests/test_feature_197.rs and register it in mod.rs.
• Implement tests for the standard execution flow (happy path).
• Implement tests simulating malicious actors and unauthorized access attempts.
• Verify that proper events are emitted during state changes with exact arguments.
• Ensure that Soroban storage is correctly rolled back when functions panic.

Acceptance Criteria ✅

• The test suite runs successfully with cargo test without any warnings.
• Coverage includes 100% of the new feature execution paths.
• Edge cases for boundary values and uninitialized states are handled appropriately.
