Pull request overview

This PR updates the Azure Managed Lustre recorded-test setup by removing the no-longer-needed recording “fix-up” script and switching the tests to use a shared helper for fast playback polling, along with updating the referenced assets tag for refreshed recordings.

Changes:

• Deleted the Fix-TestRecording.ps1 script that previously removed consecutive InProgress responses from recordings.
• Updated Managed Lustre live tests to use a centralized PollInterval(...) helper (1ms in playback, configurable in live/record).
• Bumped the assets.json tag to point at the regenerated Managed Lustre recordings in the assets repo.
