[taped] Add metric to track drive session state

Description

This MR:

• Adds two new metrics:
  • cta.taped.mount.type
  • cta.taped.drive.status
• Ensures the CI runs with telemetry enabled in test_client.sh (otherwise we never test these code paths)
• Fixes a few SonarCloud issues (e.g. deleting copy/move constructors)
• Removes some unused variables in MigrationMemoryManager

Checklist

• Documentation reflects the changes made.
• Merge Request title is clear, concise, and suitable as a changelog entry. See our contributing docs
