fix: Redact uid field and delete records for retired users from support_historicalusersocialauth

[Akanshu-2u]

Description:

Ensures PII in django-simple-history snapshots of social auth records is redacted before deletion during user retirement.

Changes:

• Add redact_and_delete_historical_social_auth utility that bulk-redacts uid and clears extra_data before bulk-deleting rows.
• Invoke the utility from LMSAccountRetirementView.post() in the retirement workflow.
• Gracefully skips on deployments where the support app is not installed.
• Add and strengthen tests across test_utils.py, test_retire_user.py, and test_retirement_views.py using the shared assert_redact_before_delete helper.
