Fix CI test failures by removing authentication from workflows

- Root cause: Local dev removed auth in b2aac89, but CI workflows still had
  partial auth setup causing WaitTimeoutError in test_drop_capped_collection
  and test_drop_database tests
- Delete user creation scripts from CI (users.adm.js, users.js)
- Update util scripts to skip user creation in rsinit function
- Remove adm:pass@ credentials from mongos connections in sh/run
- Update e2etests.yml to use connection strings without credentials
- Ensures consistency: both CI and local dev now run without authentication
