Update application code to store current organization in authentication_events

Summary

Update the application code to store the current organization from the request context into the authentication_events table. This is the second step in adding organization_id as a sharding key.

Background

This is part of the effort to add organization_id as the sharding key for the authentication_events table (#561359 (closed)). After adding the column with a default value, we need to update the application code to properly populate it with the actual organization from the request context.

Implementation Details

• Identify all places where authentication_events records are created
• Update the code to extract and store the current organization from the request context
• Ensure proper handling when organization context is not available (fallback to default organization)
• Add/update tests to verify organization_id is correctly stored

Acceptance Criteria

• Application code updated to store current organization in authentication_events
• Request context properly extracts organization information
• Tests added/updated to verify correct behavior
• Verified that new records contain the correct organization_id

Related Issues

• Investigation: #553447 (closed)

Dependencies

• Requires completion of adding organization_id column with default value

Next Steps

After this is complete and verified in production, the default value can be removed (#561359 (closed)).
