fix(bulk-operations): use dynamic stack API key from testContext

Fix 401 Unauthorized errors in bulk operation tests by using the
dynamically created stack's API key from testSetup.testContext
instead of process.env.API_KEY.

The helper functions (doBulkOperation, doBulkOperationWithManagementToken,
makeManagementToken) were using process.env.API_KEY which wasn't set at
the time of execution, causing authentication failures on both dev9 and
dev11 environments.

Changes:
- Updated helper functions to use testSetup.testContext.stackApiKey
- Ensures correct API key is used for all bulk operations
- Fixes job status check failures and other bulk operation 401 errors
- Updated .talismanrc checksum for bulkOperation-test.js
