perf: Use new platform-perf DB with more user data for deletion handlers

[david-mackessy]

• use new platform-perf DB that includes extra user data for deletion handlers (noted below)
  • user data does not contain data that triggers delete not allowed exceptions as this would fail the tests
• update DELETE thresholds to reflect test running against more data
  • previous DELETE test was against users with few associations
  • detailed in perf: User delete - deletion handler veto improvement [DHIS2-21725] #24304
