Make Security::AnalyzersStatus::ProcessArchivedEventsWorker compatible with group archival

Problem

The Security::AnalyzersStatus::ProcessArchivedEventsWorker currently subscribes to ProjectArchivedEvent but doesn't handle group archival scenarios. When a group is archived, all projects within it are effectively archived, but the worker doesn't receive the appropriate events to process security analyzer status for those projects.

This is part of the broader issue tracked in epic &19492.

Solution

We need to ensure that Security::AnalyzersStatus::ProcessArchivedEventsWorker handles group archival by either:

1. Creating a new subscriber for GroupArchivedEvent (recommended approach) - Create a new worker or extend the existing one to also subscribe to GroupArchivedEvent and process all projects within the archived group.

2. Making the existing worker handle both events - Modify the current subscriber to handle both ProjectArchivedEvent and GroupArchivedEvent, though this may make the code more complex to maintain.

Acceptance Criteria

• Analyze the current Security::AnalyzersStatus::ProcessArchivedEventsWorker implementation
• Determine the best approach (new subscriber vs extending existing)
• Implement the chosen solution to handle group archival
• Ensure security analyzer status is properly processed when groups are archived
• Add appropriate tests for the new functionality
• Verify that downstream security analyzer services remain consistent when groups are archived
