Fix Integration test and lint errors

[Tarun-kishore]

Description

This PR fixes a failure in the RollupInterceptorIT.test roll up search integration test.

The test was asserting the exact error message returned when no suitable rollup job was found for a query. However, the list of missing fields in the error message is unordered, resulting in non-deterministic string output ("missing field timestamp" appearing before or after "missing field RateCodeID").

This caused the test to fail intermittently due to strict string comparison.

This PR also fixes some ktlint errors by running ktlint --format

---

Fix

• Updated the test assertion to validate the presence of expected substrings individually using assertTrue() instead of relying on exact ordering via assertEquals().
• Ensures test stability while preserving correctness.

---

Testing

• Ran RollupInterceptorIT locally to confirm consistent pass.
• Verified that error message contains all expected fields:
  • missing field RateCodeID
  • missing field timestamp
  • missing sum aggregation on total_amount
