BFD-3563: Regression Suite PAC hashed MBIs query is returning no data resulting in failing tests

[malessi]

JIRA Ticket:
BFD-3563

What Does This PR Do?

This PR replaces the now-defunct PAC hashed MBIs query with a new query courtesy of @aschey-forpeople and @mjburling that returns usable data for our Claim and ClaimResponse Regression Suite tests.

Note that the query is limited to 300 results as the Regression Suites cycle through the returned data, so the MBIs will never be exhausted. This is fine for this type of test as we're strictly looking for regressions in performance due to code changes.

• Running the v2 Regression Suite locally against test, prod-sbx, and prod, verifying that:
  • 300 results are returned in all environments
  • The Claim and ClaimResponse regression tests work as expected and no errors were observed
  • The query finishes within a reasonable time (<1 second in test and prod-sbx, 1-2 seconds in prod)
