test: add regression test for TTL issue #6

[sojetunde8]

Closes #6

Summary

• The fix for this issue (partial TTL index, pre-save hook, conditional expiresAt default) was already merged via PR fix(transactions): prevent TTL index from deleting confirmed purchases and donations (#94) #103 (which closed duplicate issue [Bug] Confirmed purchases and donations deleted by the Transaction TTL index #94).
• This PR adds an explicit regression test that directly verifies the exact scenario from issue [Bug] Transaction TTL index deletes confirmed purchase records after 30 minutes #6: a confirmed transaction with a past expiresAt is not deleted by the TTL reaper.
• The test confirms the partial TTL index's partialFilterExpression: { status: "pending" } prevents the reaper from matching confirmed rows, and that the migration clears stale expiresAt values.

Scope

• Does not modify any production code — the fix is already fully implemented in src/models/Transaction.js, src/controllers/stellar/paymentController.js, and related files.
• Does not touch issues [Enhancement] Standardize API error response format across all endpoints #120 or [Enhancement] Add cursor-based pagination to search results #121 (separate PRs).

Testing

• test/ttlTransactionExpiry.test.js — added 1 new test case (does not delete a confirmed row even when legacy data has expiresAt in the past (#6)).
• Full test suite: npm test — 33 suites, 323 tests passed (pre-existing test infrastructure; no regressions introduced).

Files changed

• test/ttlTransactionExpiry.test.js — Added explicit regression test for issue [Bug] Transaction TTL index deletes confirmed purchase records after 30 minutes #6 and updated describe block to reference the issue.

Summary by CodeRabbit

• Tests
  • Added regression coverage for expired legacy transactions.
  • Verified expired confirmed transactions remain available and are corrected during migration.
  • Confirmed TTL cleanup applies only to pending transactions.

Walkthrough

The transaction TTL test suite now covers expired legacy confirmed transactions. It verifies that the TTL index targets only pending transactions, preserves the confirmed record, and removes expiresAt during migration.

Changes

Transaction TTL regression

Layer / File(s)	Summary
Confirmed transaction TTL regression test test/ttlTransactionExpiry.test.js	The test description documents the regression. New coverage verifies the partial TTL index filter, preserves an expired confirmed transaction, and confirms that migration removes its expiresAt field.
