Test – cleanup_expired_bids Return Value and State

📝 Description

This PR updates the QuickLendXError contract error type to implement Debug, resolving build failures caused by using Result::unwrap on analytics calculations that return QuickLendXError.

🎯 Type of Change

• New feature
• Breaking change
• Documentation update
• Refactoring
• Performance improvement
• Security enhancement
• Other (please describe):

🔧 Changes Made

Files Modified

• quicklendx-contracts/src/errors.rs: derive Debug for QuickLendXError alongside existing derives.

New Files Added

• None.

Key Changes

• Ensure QuickLendXError implements Debug so it satisfies the bound required by Result::unwrap in analytics-related helper functions.
• Unblocks cargo build for the quicklendx-contracts crate when calling analytics helpers that previously failed to compile due to the missing Debug implementation.

🧪 Testing

• Unit tests pass
• Integration tests pass
• Manual testing completed
• No breaking changes introduced
• Cross-platform compatibility verified
• Edge cases tested

Test Coverage

• Ran cargo build --verbose in quicklendx-contracts to confirm the library compiles successfully after adding Debug to QuickLendXError.
• Note: full test suite (cargo test) currently reports existing failures unrelated to this change and will be addressed in separate work.

📋 Contract-Specific Checks

• Soroban contract builds successfully
• WASM compilation works
• Gas usage optimized
• Security considerations reviewed
• Events properly emitted
• Contract functions tested
• Error handling implemented
• Access control verified

Contract Testing Details

• Verified that contract library compilation now succeeds where it previously failed due to QuickLendXError not implementing Debug.

📋 Review Checklist

• Code follows project style guidelines
• Documentation updated if needed
• No sensitive data exposed
• Error handling implemented
• Edge cases considered

📋 Additional Notes

• This is a narrowly scoped change focused solely on making QuickLendXError compatible with existing analytics helpers that use unwrap.

🧪 How to Test

1. From the quicklendx-contracts directory, run cargo build --verbose and confirm the build completes successfully.
2. Optionally run any analytics-related helper calls in existing tests or follow-up branches to verify they compile and link correctly.
3. (Optional) Run cargo test to observe the broader test status; note that current failures are pre-existing and outside the scope of this PR.
